LCRA TSC works to storm harden transmission lines in northern Travis County

Project will increase reliability, safety of lines going from near Mansfield Dam to north Austin

Aug. 3, 2023

TRAVIS COUNTY, Texas – LCRA Transmission Services Corporation has started construction on a key project to increase the reliability and resiliency of transmission lines traveling through parts of northern Travis County. The $43 million LCRA TSC project will storm harden more than 14 miles of high-voltage transmission lines to make them better able to withstand extreme conditions such as wind, ice and other weather-related issues. Upgraded lines can help reduce outages and minimize restoration times and costs. The project will increase the reliability and safety of the structures and conductor by ensuring the transmission lines meet or exceed current National Electrical Safety Code and LCRA TSC design standards. Large construction equipment, bucket trucks and cranes will be used in the project, and traffic may occasionally be stopped for brief periods on roads under the lines as the work progresses. Construction began in late July 2023 and is expected to continue to May 2024. The transmission lines in the project run from near Mansfield Dam off Ranch Road 620 east to the Walnut Creek Metropolitan Park area in north Austin. The lines cross U.S. Highway 183 and MoPac near The Domain shopping center. Work also will occur on a section of lines west of Spicewood Springs Road, traveling adjacent to the road northward about 1.3 miles to Old Lampasas Trail. A map of the route and more information is available at
