Austin
The I-35 Capital Express Central Project, a multi-billion-dollar infrastructure initiative, is set to substantially impact beloved city spaces throughout Austin. The construction will take place along I-35 between 290 East and Highway 71 at Ben White Boulevard, aiming to alleviate traffic congestion and improve connectivity through downtown Austin.
Key Components of the Project
This ambitious project includes lowering the roadway of I-35 and adding two additional non-toll lanes in each direction. To facilitate this work, the parking lot situated under the I-35 bridge will be closed for equipment storage, affecting access for many local residents and visitors.
The renovations will also involve rebuilding east-west cross-street bridges and creating new pedestrian and bicycle paths. Construction on the Martin Luther King Jr. Boulevard bridge segment has already commenced, and larger bridge replacement preparations are expected to kick off in 2026. This will lead to the closure of short segments of the trail for about a week, up to three times a year, prompting detours for both north and south shores of the trail, though specific locations for these detours have yet to be established.
Community Impact and Concerns
Community members, including local residents who often utilize the area for activities like kayaking and fishing, have expressed concerns regarding the construction’s impact on their recreational spaces. Residents are particularly worried about the disruption caused by temporary closures during construction phases, even as they recognize the long-term advantages of the infrastructure improvements.
TxDOT has assured that efforts will be made to minimize disruption for trail users, with a commitment to maintaining trail access as much as possible. Public notifications will be set up to inform residents about upcoming detours and closures throughout the duration of the project.
Project Timeline and Additional Features
The entire I-35 Capital Express Central Project is estimated to cost around $4.5 billion and is expected to be completed by 2033. As part of the project, the MLK Boulevard exit will be permanently closed, and major phases have been organized to ensure that three lanes of traffic remain open at all times during construction to minimize traffic disruption.
Moreover, the design emphasizes pedestrian and cyclist safety with plans for enhanced crossings, allowing for safer access across I-35. Efforts will also focus on integrating public park spaces over sections of the highway to reconnect neighborhoods that may have been divided by previous infrastructure developments.
Environmental Considerations
TxDOT is currently engaged in litigation concerning potential displacements and environmental impacts related to this extensive project. As a result, local authorities are closely monitoring developments to ensure that community concerns are addressed responsibly and effectively.
