183A Toll Shield Construction Advisory: 183A Frontage Road Resurfacing Project

 Work began the week of July 28, 2014 on an asphalt maintenance project on the north and south  bound frontage lanes of 183A in Williamson County. The project will remove and replace the top two  inches of the 18-inch thick pavement along the frontage roads. The resurfacing process is expected to be finished by the end of October 2014. While some work will occur at night to minimize disrupting traffic, motorists should be aware of daytime lane closures during the construction period. 


UPDATED : Sunday, October 12 – Thursday, October 16 from 8:00 pm. to 6:00 a.m.

  • Thursday, October 16th there is an anticipated closure of the non-tolled northbound exit ramp to New Hope. 
  • Various lane closures on the 183A northbound frontage road from FM 1431 to New Hope Road.
