Mobility Authority Begins Process of Resurfacing Existing Lanes of U.S. 183

Rolling Closures and Roadwork May Impact Drivers and Residences Overnight

(Austin, Texas) – Beginning this week and continuing throughout the next several months, the Central Texas Regional Mobility Authority (Mobility Authority) will be staging rolling closures of existing mainlanes on U.S. 183 between FM 620 and MoPac (Loop 1), in order to begin pavement grinding as a part of resurfacing the roadway for the 183 North Mobility Project. The closures are anticipated nightly between the hours of 9 p.m. to 5 a.m. Monday – Thursday and 9 p.m. to 8 a.m. Friday – Saturday. The work will begin southbound on U.S. 183 and continue in 2-mile segments. Night lighting will be used to keep workers safe, and the noise level anticipated from the resurfacing of the roadway will stay within OSHA guidelines, and be about the sound of a garbage truck.

Called Next Generation Surface Grinding (NGCS), the resurfacing process will be performed in stages throughout the different phases of construction. NGCS is a texture treatment that “can be utilized for both new construction and rehabilitation of existing surfaces,” according to a report by the Texas Department of Transportation (TxDOT). NGCS is a smooth concrete pavement surface that “provides desirable friction characteristics,” cites the report. This innovative approach addresses multiple needs: It improves skid resistance, promotes better drainage and makes the roadway more consistent and level for a safer and more comfortable ride along the 183 North Mobility Project corridor.

Variable message signs will be placed in advance of the closures to notify drivers of anticipated delays. Drivers are urged to exercise caution and consider alternate routes for nighttime travel.

More information, including scheduled lane closures, will be updated on the project website: 183north.com.
