Few things get local greenspace lovers more hyped than the upcoming improvements and beautification of our beloved Memorial Park — which is currently undergoing a major transformation. While many of the updates and facelifts are years off, one of the most innovative ventures has reached a new milestone in the much-anticipated Land Bridge and Prairie project.

Installation of the first tunnel arches has started as of December 9, according to the Memorial Park Conservancy. Marked by two separate, 35-foot tall mounds, the Land Bridge will serve as a major connector for park users and wildlife between the north and south sides of the park, Additionally, it will offer new gathering spaces with scenic views of Houston and the project's expansive prairie network.

Once the project is completed, vehicular traffic will traverse a new alignment of Memorial Drive via tunnels through the Land Bridge — two tunnels below each of the mounds (one for each direction of travel), according to a press release. The arch segments now being erected south of existing Memorial Drive are for the two tunnels through the eastern-most mound.

Next up will be erection of the west mound arches; all tunnels are slated for completion and open to traffic by fall of 2021.

These tunnels boast an innovative edge. While most are built through existing hillsides or below ground, the Land Bridge tunnels will be set at the same grade as the existing roadway, prior to installation of the earthwork for the mounds, per a release. The tunnels through the east and west mound measure 400 feet and 560 feet long respectively and are made up of some 620 separate panels, each of which weighs just under 50,000 pounds.

While excitement is looming, traffic on Memorial Drive is no doubt a concern. Sources at Memorial Park Conservancy assure that Memorial will remain open throughout the duration of Land Bridge and Prairie construction. Within the project area, traffic has been reduced from three lanes to two each way.

All lanes will reopen in fall 2021 once the new Memorial Drive alignment through tunnels is complete. The new road alignment with three lanes restored each way will be complete in September 2021, while the Land Bridge is slated for substantial completion by October 2022.

Meanwhile, trees removed from the Land Bridge and Prairie project area (a major concern for locals) will be relocated in areas of the park designated for reforestation, or repurposed as either compost or toewood for streambank stabilization, in keeping with the Master Plan provisions.

Houston park breaks ground on innovative land bridge

now building

Last week, Memorial Park made headlines when it triumphantly opened its lush and verdant Eastern Glades. The 100-acre destination transformed largely inaccessible green space into a destination offering up picnic areas, native wetlands, a savanna, a pine-hardwood forest, green spaces, and miles of accessible trails.

Now, the Memorial Park Conservancy has announced that construction has begun on Memorial Park's Land Bridge and Prairie project. The 100-acre project, slated for completion in late 2022, will create a new community space with enhanced recreation opportunities for park users with "unmatched vantage points of urban skyline views," according to a press release. Memorial Park's prairie, which adjoins the Land Bridge to the north and the south, aims to re-establish endangered native Gulf Coast prairie, savanna, and wetlands.

The Land Bridge and its corresponding prairie are part of the Memorial Park Master Plan, made possible by a $70 million gift from the Kinder Foundation, and associated the Ten-Year Plan.

Commuters, no need to worry: Memorial Drive will remain open throughout the duration of Land Bridge and Prairie construction. Traffic will be reduced from three lanes to two each way beginning September, while a new section of Memorial Drive and the tunnel arch structures for the Land Bridge are completed directly south of the operating lanes.
All lanes will reopen in fall 2021 once the new Memorial Drive alignment through tunnels is complete, according to a release.

Additionally, per the conservancy, the Land Bridge will:


Provide safety and connectivity
This will benefit both humans and animals crossing Memorial Drive. The Land Bridge will establish two dynamic greenspace connections over Memorial Drive that reunite the north and south sides of the Park while expanding the existing trail network and providing increased connectivity within the Park. While the Land Bridge will provide connectivity for Park visitors and wildlife over Memorial Drive, a stream corridor constructed through the Prairie and a culvert will provide connectivity under Memorial Drive. Together these elements will provide much-needed wildlife connectivity within Houston's largest urban wilderness park and to the natural Buffalo Bayou corridor.

Restore nearly 45 acres of native coastal prairie
This will establish a more resilient ecology during natural disruptions and improve animal habitats. Native coastal prairie is one of the most endangered ecosystems in North America, with less than 1 percent of its historic range remaining today. These forthcoming ecosystems will be home to numerous species of flora and fauna.

Create a new destination for visitors
New opportunities include nature education, leisure walking, interval running and cycling, stargazing, relaxing, and more.

Improve stormwater management
The project will detain stormwater that flows through Memorial Park to Buffalo Bayou during heavy rain events, lessening the impact of peak storms. A stream channel constructed through the site, along with the network of native prairie and savanna, will support greater regional biodiversity and act as a green sponge, helping to absorb and clean stormwater. The constructed wetlands will help to purify water and reduce roadway pollutants that would otherwise be released into the watershed.

"From aiding with critical stormwater management to granting people and wildlife safer crossing over Memorial Drive to providing a dynamic outdoor destination for all visitors, the Land Bridge and Prairie will be an asset not just for Memorial Park but for all Houstonians," said Mayor Sylvester Turner in a statement. "It's about unifying both sides of the Park and giving people a new landmark that they can be proud of and use to enjoy nature."

3 ways the Memorial Park Conservancy renovations are innovative

Park of the future

Memorial Park is undergoing a huge transformation that is mixing a little bit of old with the new.

The Memorial Park Master Plan includes adding breathtaking new projects — like water features, a new athletic complex, and more — as well as conservation efforts that restore parts of the land that were native coastal prairie. The project is a collaborative effort between Memorial Park Conservancy, Uptown Houston TIRZ, and Houston Parks and Recreation Department to redevelop the 1,500-acre park.

The Master Plan is set to deliver a series of projects ahead of 2028, and there are a few initiatives that are innovative and different from other urban parks' transformations, notes MPC's president and CEO Shellye Arnold.

The Land Bridge

A big part of Memorial Park's transformation is restoring the park to native species and ecosystems.

"We're taking ball fields, parking lots, and roads and converting them back to what was here — native wetland coastal prairie," Arnold says. "This serves important stormwater purposes."

In order to connect two native coastal prairie lands on either side of Memorial Drive, MPC is building a unique 30-foot-high land bridge the size of three-and-a-half football fields. The space will be large enough that you don't even realize you're standing over a busy street, Arnold says.

The prairies will serve an important purpose for rainwater collection — a growing need within the city of Houston.

"We're channeling [rainwater] into this prairie where some of it can be absorbed, cleansed, slowed down," says Arnold. "And then what doesn't get slowed down and absorbed can flow through the prairie [on the other side], which is even bigger."

The Land Bridge also serves another purpose that park goers have wanted, Arnold says: Connectivity.

"[They] want access across the Memorial Drive — [they] want to safe access, and so this is the response. It's a pretty bold and visionary response," Arnold says.

BioCycling

In 2011, a major drought decimated the park and areas saw losses of 50 to even 90 percent of the canopy of trees. MPC and its team saved what could be saved, and the rest is serving a new purpose to the park.

"We took the trees that we lost on the drought that people felt such a tremendous loss for and ground them all up, and they are in a biocycle in a two-acre area in the back of the park," Arnold says.

The soil created — some of which includes manure from the animals at the Houston Zoo — has already been used on some plants in the park, and Arnold says those plants are thriving.

"It's cool that those those trees are giving life to the park," Arnold says.

Invasive species of trees that are plucked from out of the park are also being ground up and used in the same way.

"There isn't anything this big like this in an urban park setting like this kind of recycling effort," she says.

The biocycling process is scalable too.

"We could open this up to other organizations," Arnold says. "It's so much better ecologically to take trees and grind them up and use it inside the space rather than haul them out to landfill way outside of town and dump them."

The benefit to the program is that MPC can retain some of the soil it produces for these other organizations and use it on site.

Biodiversity initiatives and research

When putting the plans in place, MPC and its partners called on 25 of the best ecologists, as well as 50 more park and other types of consultants specializing in everything from insects and wildlife to prairies and trees.

Just as the Land Bridge is creating new prairie space, other initiatives throughout the park will be focused on eliminating invasive species and bringing back the natural ecosystem of the park.

The Easter Glades project, which is set to deliver next year, will have a habitat for fish, and will not allow any fishing or boating. Carolyn White, conservation director at MPC, is working with the Texas Wildlife Association to bring in the right species of fish.

Arnold says that MPC works with other organizations in an innovative way to bring native plants into MPC, since the park has the space for these organizations to use to cultivate and propagate plants.

"They bring their native plants and they grow them with their volunteers, and they leave us a little bit here," Arnold says. "We could never buy enough native plants to go inside this park."

New UH survey reveals concerns over AI data center growth in Houston

data findings

A new report out of the University of Houston shows that area residents remain wary of the long-term effects of operating data centers.

The recent survey from the University of Houston’s latest SPACE City Panel, conducted by the Center for Public Policy at the Hobby School of Public Affairs, shows that while 85 percent of Houston-area residents use AI, nearly 63 percent oppose the construction of AI data centers within 1 mile of their homes.

Respondents’ concerns centered around data centers’ high energy demand and the area’s power grid reliability. According to the survey, 32 percent of residents who oppose local data center projects would be more likely to support the centers if they relied on renewable energy over fossil fuels.

“Respondents understand that AI can bring economic and educational benefits, but they are also concerned about the physical infrastructure needed to fuel AI, especially data centers,” Soran Mohtadi, post-doctoral fellow at the Hobby School and a researcher on the report, said in a news release. “This physical infrastructure demands more electricity and water, leading to environmental impacts.”

Experts estimate that 6.5 gigawatts of data center capacity will be added to the Texas grid by 2030. And Houston’s data center capacity is predicted to more than double by 2028.

The Electric Reliability Council of Texas also projects electricity demand could reach 218 gigawatts by 2031, which would be more than double the record peak set in August 2023. Data centers are expected to account for 86 gigawatts of that new demand.

Survey respondents also said they are concerned about the state's future water supply, given the large amounts of water that data centers need to stay cool.

In terms of who’s responsible for that issue, 57.6 percent of respondents said they put the onus on Texas lawmakers, while 31.5 percent say tech companies should be responsible.

Additionally, more than 75 percent of respondents believed that data center developers and technology companies—not residents—should bear the cost of infrastructure upgrades to support data centers.

“Every decision legislators make has implications on residents’ everyday lives and local infrastructure now and in the future,” Maria P. Perez Arguelles, lead researcher on the report and research assistant professor at the Hobby School, added in the news release. “This issue is going to become more important in years to come, so this is just the beginning.”

Houston-born Cemvita makes breakthrough in sustainable fuel production

clean fuels

Houston-based biotech company Cemvita announced that it recently reached a critical milestone in the development of its FermOil product, which can be used to create Sustainable Aviation Fuel (SAF) and other renewable fuels at industrial scale.

The company shared in a news release that it completed a 75,000-liter industrial fermentation run at Belgium's Bio Base Europe Pilot Plant.

The campaign achieved target technical metrics for the production of FermOil, Cemvita’s renewable natural oil (RNO). FermOil is produced from industrial crude glycerin, an industrial byproduct, as opposed to traditional sugar-based feedstocks used in many bio-oil fermentation processes. It's designed to be a drop-in feedstock for creating SAFs.

Cemvita had previously advanced its FermOil production process through multiple scale-up stages before successfully reaching the 75,000-liter demonstration campaign, according to the company.

“This is not just a fermentation milestone,” Moji Karimi, CEO at Cemvita, said in the release. “It is a blueprint for how existing industrial infrastructure can evolve into circular bioeconomy infrastructure. Every biodiesel plant generating crude glycerin is a potential platform for renewable natural oil production.”

The milestone also supports the deployment of Cemvita’s industrial biomanufacturing platform, FermWorks, which integrates with existing energy and industrial infrastructure to turn waste carbon streams into SAFs and other materials. According to the release, Cemvita plans to move forward with commercial deployment discussions with partners in Brazil, Europe and in the UK. Cemvita already has a partnership with the Brazilian sustainable research institution REMA.

“We are proud to support innovative companies like Cemvita in scaling breakthrough industrial biotechnology solutions,” Hendrik Waegeman, head of business operations at Bio Base Europe Pilot Plant, added in the release. “Successfully operating at the 75,000-liter scale using a feedstock such as crude glycerin highlights both the maturity of the technology and the quality of the scale-up execution achieved by the Cemvita team.”

Eli Lilly scoops up Houston biotech startup in $300 million deal

big pharma deal

Pharmaceutical giant Eli Lilly has acquired Houston biotech startup CrossBridge Bio, which develops antibody-drug conjugates for cancer, in a deal worth up to $300 million. The deal was celebrated by TMC Venture Fund and the University of Texas Health Science Center at Houston last week.

CrossBridge, founded in 2023, is developing ADCs based on research by Kyoji Tsuchikama and Zhiqiang An, both of UT Health Houston. Tsuchikama is an associate professor of medicinal chemistry and a globally recognized ADC pioneer, and An is a professor of molecular science and vice president of drug discovery.

Antibody-drug conjugates (ADCs) are a potent combination of targeted therapy and chemotherapy that kills cancer cells while saving healthy tissue.

Clinical trials for CrossBridge’s primary ADC candidate, CBB-120, are expected to start this year, pending approval from the U.S. Food and Drug Administration (FDA).

“I’m proud of how well our team has executed and advanced our platform in such a short time since the company’s founding,” Michael Torres, co-founder and CEO of CrossBridge, said in a news release. “By becoming a part of Lilly, a leader in patient-focused therapeutic development, we are well-positioned to further accelerate the clinical potential of this approach.”

Under the Lilly deal, CrossBridge shareholders were expected to receive an upfront payment along with a follow-up payment based on the achievement of certain milestones.

In 2024, CrossBridge closed a $10 million seed round. Among the investors in CrossBridge are the Texas Medical Center Venture Fund, CE-Ventures, Alexandria Venture Investments, Portal Innovations, Linden Lake Labs, and the Cancer Prevention and Research Institute of Texas (CPRIT). It was formed in TMC Innovation’s Accelerator for Cancer Therapeutics program."Built within the TMC ecosystem, CrossBridge Bio grew with the support, funding, and resources that helped shape its trajectory. TMC led the company's early financing and watched it evolve from its earliest days to its acquisition by Eli Lilly," William McKeon, president and CEO of the Texas Medical Center, shared in a LinkedIn post. "[This is a] strong reminder that breakthrough science and the right early backing can change what’s possible."
