Major Changes Ahead for Austin’s I-35 as Capital Express Central Project Set to Impact Popular City Spaces

Austin, Texas — A significant infrastructure project along I-35 is underway in Austin, with substantial construction expected to alter key city areas and impact daily commuting, recreation, and local neighborhoods. The Capital Express Central Project, a multi-billion-dollar initiative, aims to improve highway capacity, safety, and connectivity across downtown Austin, but it will also bring temporary disruptions to residents and visitors.

Scope and Objectives of the Project

The I-35 Capital Express Central Project spans approximately eight miles of freeway expansion. Its primary goals are to lower the roadway to improve flood management, create two non-toll lanes in each direction, and upgrade existing infrastructure. The project is designed to enhance traffic flow, reduce congestion, and provide safer and more accessible routes for pedestrians and cyclists.

An essential component of the project involves rebuilding east-west cross-street bridges and incorporating new pedestrian and bicycle pathways. These improvements aim to reconnect neighborhoods that have been divided by the highway, fostering better safety and accessibility for non-motorized users.

Construction Timeline and Funding

Estimated to conclude in 2033, the project has a planned budget of approximately $4.5 billion. To minimize traffic disruptions, construction phases are carefully scheduled and organized, with measures to keep at least three lanes of traffic open in each direction during the process.

Impact on City Spaces and Local Residents

The project will significantly impact well-used city spaces, particularly along the section between 290 East and Highway 71 at Ben White Boulevard. One notable change includes the closure of the parking lot located under the I-35 bridge, which has historically served as a popular spot for kayaking, fishing, and community gatherings.

Furthermore, TxDOT plans to close short segments of the trail on both the north and south shores for approximately a week, up to three times a year, as part of bridge replacement preparations beginning in 2026. While exact detour routes are yet to be finalized, officials assure that efforts will be made to keep trail access continuous and minimize inconvenience for outdoor enthusiasts and daily commuters.

Many local residents, including those who enjoy outdoor activities, express concern over the temporary closures and construction noise. For instance, residents who regularly kayak and fish in the area have voiced their worries about how the construction could affect their access and local ecology. Nonetheless, some acknowledge that these temporary inconveniences are necessary for long-term improvements.

Traffic Changes and Closure of Key Exits

A major alteration within the project is the permanent closure of the MLK Boulevard exit, which is expected to affect traffic routing and local access points. Construction on the Martin Luther King Jr. Boulevard bridge segment has already begun, marking an early phase of the project.

Additional Infrastructure Enhancements

Beyond highway expansion, the project includes significant enhancements for pedestrian and cyclist safety—such as improved crossings and wider paths—aimed at encouraging alternative transportation modes. A unique feature involves incorporating public park spaces over sections of the highway, designed to reconnect neighborhoods and create new community recreational areas.

Legal and Environmental Considerations

In parallel to construction efforts, TxDOT is engaged in ongoing litigation regarding potential displacements and environmental impacts. These issues highlight the challenges involved in large-scale urban infrastructure projects, which must balance growth with ecological preservation and community interests.

Public Engagement and Next Steps

Ensuring community awareness remains a priority, with public notifications scheduled to inform residents and trail users about upcoming detours and closures. As the project progresses, Austin officials emphasize that their focus is on minimizing disruptions while delivering long-term benefits that include reduced congestion, improved safety, and enhanced city connectivity.

As Austin moves forward with this ambitious initiative, the city anticipates a transformation of its transportation landscape, aiming to create a more integrated and accessible urban environment—albeit through temporary challenges and adjustments for residents and visitors alike.
