Crews were beginning work Monday, July 29, at the intersection of New Hope Drive and Ronald Reagan Boulevard stretching to just south of the intersection of Ronald Reagan and Crystal Falls Parkway. There will be an inside lane closure in the work area on the northbound side of Ronald Reagan.
At the New Hope and Ronald Reagan intersection, traffic is expected to be stopped one time for approximately 5 minutes to pass a rope across the northbound lane of Ronald Reagan and CR 272. At the Caballo Ranch Boulevard and Ronald Reagan intersection, traffic will be stopped one time for approximately 5 minutes to pass a rope across the intersection, inside the median right of way. No traffic stops between the hours of 8:30 a.m. and 5 p.m. are anticipated.
Work in this location is scheduled to take place through Saturday, Aug. 24. The current work schedule is 6 a.m. to 4:30 p.m., and closures are expected to be removed before 5 p.m. each day. No impediment to southbound traffic flow is expected during this work.
July 9, 2019
Construction crews will be working along RR 2243 and Ronald Reagan Boulevard in Leander on Wednesday, July 10. Between 7 a.m. and 4:30 p.m., crews will pull rope across RR 2243 and later, across Ronald Reagan Boulevard. This will require traffic to be stopped on Ronald Reagan twice for about five to 10 minutes each time: once near RR 2243 and once near Hero Way.
The inside lane of southbound Ronald Reagan is expected to be closed from Hero Way to RR 2243 throughout the work on Wednesday, and guard buckets and boom trucks will be in use.
The work could potentially continue into Thursday, July 11. If so, this page will be updated with the location and any potential impacts to traffic.
Crews plan to install the new wire the week of July 15. No traffic stops are expected during that time, but additional inside lane closures are possible. Police will be on the scene in case a traffic stop becomes necessary to safely complete the work.
June 10, 2019
Construction work over U.S. Route 183A was delayed a couple of days after severe weather blew through the area Sunday night. The construction is now scheduled to be completed by 5 a.m. Thursday, June 13. Traffic could be stopped for brief periods a few times a night between 9 p.m. and 5 a.m. on Monday and Tuesday, June 10 and 11.
Installation of the transmission line along a section of the project that parallels Hero Way is scheduled June 13-21 between 7 a.m. and 5:30 p.m. No additional lane closures are anticipated.

Pole, transmission line installation begins
Crews have begun installing poles on the portion of the project between the Leander and Spanish Oak substations along Ronald Reagan Boulevard. Clearing of the right of way will continue on the north and south sides of Ranch to Market Road 1431 this month. Installation of the transmission line along a section of the project that crosses U.S. Route 183A at Hero Way is scheduled June 7-10 between the hours of 9 p.m. and 5 a.m. As part of this, traffic will be stopped at the intersection four times on Friday night, for about 10 minutes each time.
May 3, 2019
Construction on the new transmission line is expected to continue through March 2020. Over the next month, transmission line work will continue in Leander and Cedar Park, primarily along Hero Way, Ronald Reagan Boulevard and County Road 272. Additionally, work activities likely will begin along FM 1431, stretching into Round Rock. The work can involve the use of large trucks and equipment and other machinery or vehicles typically used in transmission line construction projects.
Standard hours for work on this project are Mondays-Fridays from 6 a.m. until around 5 p.m. and Saturdays 7:30 a.m. until about 4:30 p.m. We make efforts to limit weekend work; however, due to weather-related and other issues, work during those hours is necessary from time to time to help facilitate efficient completion of the project.

Application filed with the Public Utility Commission of Texas
LCRA TSC on April 28 filed
an application with the PUC to amend its Certificate of Convenience and Necessity (CCN) for the Leander-Round Rock Transmission Project. The application includes data on 31 alternate routes that range from approximately 12 to 21 miles long and are estimated to cost from $67.8 million to $99.6 million (including the proposed transmission and substation facilities). Numerous other routes could be created by combining the filed segments into additional routes. The route order is numerical and does not signify any preference on LCRA TSC’s part as to which route is ultimately approved.
In its application, LCRA TSC identifies Route 31 (consisting of links D-F-X5-Z5-A6-C6-F6 (Substation Site 2-8)-M-P-Q-Q4-V-W-T4-X-J1-A5-L1-P1-T1-V5-D2-(Substation Site 1-7)-K4-J2-Q2-S2-Y2-Z2-P5-B3-C3-E3-G3-I3-J4) as the filed route that LCRA TSC believes best addresses the routing requirements of the Public Utility Regulatory Act and the regulations of the Public Utility Commission of Texas.
The identification of Route 31 as the route that best addresses the PUC’s routing criteria was based significantly on its relatively low estimated cost and input provided by local elected officials, including resolutions adopted by the cities of Leander, Cedar Park and Round Rock, and on LCRA TSC’s evaluation of the overall manner in which Route 31 impacts the community by using existing transmission line corridor and following existing rights of way for a significant portion of its length, minimizing newly affected habitable structures within proximity to the project, and avoiding the Brushy Creek environmentally sensitive area. Use the interactive mapping tool to view alternate route segments and property line information (high-speed internet access is recommended).
LCRA TSC hosted two open houses in Cedar Park and Leander in October 2015 to gather input and inform stakeholders about the project. Over 615 people attended one or both of the open houses. Since the open houses, LCRA staff met with numerous local and state elected officials and school districts, school classes, municipal utility districts, and developers and commercial property owners. LCRA staff have also met with hundreds of landowners and homeowners associations. Subsequent to the open houses, LCRA TSC received more than 1,200 emails from interested parties and stakeholders. The cities of Leander, Cedar Park and Round Rock all passed resolutions generally supporting a transmission line route for the project along FM 1431, Sam Bass Road and Leander Road.
The application identifies 16 possible alternate substation sites; eight in each of two substation siting areas. Portions of some of the proposed route alternatives include rebuilding existing LCRA TSC transmission lines located north of the Round Rock substation.
In conjunction with filing the application on April 28, 2016, LCRA TSC mailed letters to all landowners whose land is crossed by an alternative route or who own property located within at least 300 feet of an alternative route. The notices include information about how those property owners can participate in the proceeding. LCRA TSC will also publish public notifications in area newspapers as required by PUC regulations. On April 28, 2016, LCRA TSC also provided notices to municipal, county, state and federal elected officials. The intervention deadline is June 13, 2016. If approved by the PUC, the transmission line, Substation 1 and Substation 2 are scheduled to be energized by December 2019.
