Ongoing projects
Ronald Reagan Boulevard lane widening
Project: Work is widening 7 miles of roadway on Ronald Reagan Boulevard from FM 3405 to SH 29 with a northbound-only section and a separate two-lane southbound road.
Update: Construction is currently underway.
San Gabriel Parkway extension
Project: Work is extending San Gabriel Parkway eastward from Isaias Drive to Ronald W. Reagan Boulevard between Palmera Ridge and Palmera Bluff subdivisions as an arterial roadway.
Update: Construction is ongoing, and a traffic signal at San Gabriel Parkway and Ronald Reagan Boulevard is expected to be operational by early 2026.
Legacy Ranch Drive expansion
Project: Work is expanding roughly 0.6 miles from Seward Junction North Loop (CR 258 and CR 260) to the CR 258 extension east of US 183 with two new signals, pavement overlay and right-turn lanes into a future Liberty Hill ISD school site.
Update: Contractors broke ground on the project March 6.
RM 2243, Hero Way controlled-access highway
Project: Work is reconstructing and widening RM 2243 and Hero Way into a divided, controlled‑access highway from 183A Toll to Southwest Bypass. The existing rural two-lane roadway will be expanded into two main lanes running in each direction alongside two three-lane frontage roads.
Update: Crews broke ground on the first phase of the project in late January, working to construct the first frontage road from 183A Toll to Garey Park.
