The city of Austin’s Capital Delivery Services has partnered with Austin Energy, pushing forward improvements for the South Lamar Boulevard Corridor project, which includes upgrades to electrical distribution wires and replacing utility poles.

The upgrades are intended to increase energy capacity for the growth along this corridor as well as maintain safety and reliability, according to project information from Austin Energy.

What you need to know

An update from Capital Delivery Services states the construction on the South Lamar Corridor Reconductoring project will begin July 7 and be completed in three phases.
  • Phase 1: West Oltorf Street to West Mary Street
  • Phase 2: West Mary Street to Treadwell Street
  • Phase 3: Treadwell Street to Barton Springs Road
Construction will take place weekdays from 7 a.m.-7p.m. on both the right and left lanes. The middle lane will be open for both north and southbound traffic. Each phase is expected to last two months; however, the timeline for construction is dependent on weather conditions.

Bike lanes, pedestrian traffic and Americans with Disabilities Act-compliant access will be limited during construction, according to the update. Bus stops along South Lamar from West Oltorf Street to Barton Springs Road may also be temporarily closed or relocated. Capital Metro will inform riders of any temporary closures or detours.


Power outages are not expected, but if any outages are required, Austin Energy will notify affected customers.

What else?


The city of Austin has allocated $482 million from the 2016 Mobility Bond for improvements throughout key corridors in the city, including South Lamar Boulevard, which spans from Riverside Drive to Hwy. 290.

The mobility enhancements are expected to reduce traffic congestion, improve public transit efficiency, and create continuous ADA-compliant sidewalks and bike paths along the entire length of the corridor.

Preliminary road improvements at the intersection of West Mary Street and Evergreen Avenue are expected to begin this fall. Engineering plans indicate a new roundabout as well as upgrades to bike and pedestrian pathways.
