I-35 Bridge Reconstruction and Southwest Austin Detours Impact Friday Commute

Morning Commute Overview

Austin commuters should prepare for a complex Friday morning travel window as major infrastructure projects reach critical phases across the city. On this Friday, February 27, 2026, the primary focus for drivers remains the central corridor and the ongoing transformation of the Oak Hill area. While some relief has arrived with the opening of new lanes in Southwest Austin, long-term construction near Lady Bird Lake continues to reshape traffic patterns for those entering the downtown core.

Major Highway and I-35 Updates

The I-35 Capital Express Central project is currently in a high-activity phase, specifically focusing on the reconstruction of the bridges over Lady Bird Lake. Commuters should be aware that the existing northbound Riverside Drive exit and the Holly Street entrance and exit ramps remain permanently closed to facilitate this $4.5 billion expansion. To mitigate delays, TxDOT has opened a new Riverside Drive bypass lane and a temporary Holly Street exit and U-turn. Drivers are urged to follow updated signage as these patterns are now the standard for the duration of the bridge work.

In Southwest Austin, there is positive news for those traveling from Dripping Springs toward the city. The eastbound US 290 mainlanes between RM 1826 and William Cannon Drive are now open, allowing through traffic to bypass several traffic lights at the historic "Y" intersection. However, work continues on the SH 71 flyovers, with crews actively pouring concrete this week. Expect localized congestion as equipment moves through the work zone near the US 290 and SH 71 interchange.

CapMetro Transit Alerts

Public transit riders should plan for several active detours affecting bus routes across the city today. Capital Metro has confirmed that the following construction-related detours are in effect:

• Westgate Waterline Installation: Detours remain active through the end of February, affecting routes in the Westgate area.
• Lady Bird Lake and Wickersham/Riverside: Ongoing waterline work has triggered detours for routes serving the Riverside corridor and Lady Bird Lake vicinity.
• Slaughter Lane and I-35: Construction on the southbound frontage road continues to impact local bus stops and route timing.
• Ross and Pearce Road: Significant road construction detours are active in this area and are expected to last through late spring.

Local Roadworks and Hazards

Drivers on North Lamar Boulevard should watch for crews near the North Austin Muslim Community Center, where a new pedestrian beacon project is being finalized. Additionally, for those planning a late-evening trip toward San Antonio, TxDOT will begin permanent striping on IH-10 eastbound starting at 9:00 PM tonight between the FM 1518 exit and the Zuehl entrance ramp. This work is weather-dependent but may cause significant overnight delays for regional travelers.
