The Texas Department of Transportation has plans to improve the bottleneck of traffic that is happening at Cheek-Sparger Road and SH 121 in Colleyville because of improvements being made to the north and south of this area. Currently traffic shifts down to two lanes in both directions at this location, which makes traveling in the afternoons difficult as congestion occurs along this road. TxDOT officials have said that the plan is to widen SH 121 at Cheek-Sparger Road. Crews will add an additional lane between SH 183 and Glade Road. The lane will be available to motorists during peak times, similar to sections of the President George Bush Turnpike. What this means is that this additional lane will act as a shoulder during non-peak driving times, and signage will be used to indicate when motorists can travel on it during peak times. This will be a permanent feature. This project is expected to be awarded in 2019, and the estimated construction cost is $26 million.
