Marshall Ford to McNeil Transmission Line Storm Hardening Project
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.
The lines being worked on go from near Mansfield Dam off Ranch Road 620 eastward crossing Highway 183 and Mopac in north Austin to the Walnut Creek Metropolitan Park area. Work will also occur on a section of the lines just west of Spicewood Springs Road, traveling adjacent to the road northward about 1.3 miles to Old Lampasas Trail.
Latest Update – September 2023
Overnight work on the project is scheduled Tuesday, Sept. 26-Thursday, Oct. 5. This work will occur on a portion of the transmission line that starts east of Mansfield dam and ends west of FM 2222. This segment of transmission line runs alongside RR 620 at various points, and it crosses RR 620 at Steiner Ranch Boulevard.
Crews will use nighttime lighting and large equipment and vehicles. There will be activity near some residential areas, and residents may notice additional traffic and noise. The overnight work will occur from 7 p.m. to 5:30 a.m. Traffic controls will be in place as needed. Weather conditions or other factors can cause delays in the work schedule in some cases.
