The Texas Department of Transportation recently conducted a speed study on SH 121 Business from the Sam Rayburn Tollway to I-35 in Lewisville.
TxDOT recommended decreasing the speed limit in the segment of SH 121 between the tollway and 370 feet south of Valley Ridge Boulevard from 60 mph to 50 mph, according to the Nov. 1 agenda item.
The study was not prompted by a citizen or an incident. TxDOT conducts speed studies every three to four years, according to Lewisville Traffic Specialist Jason Walker. The agency used 85th percentile speeds to determine the recommended speed limit.
An amendment to Section 15-35 of the Lewisville City Code is required to establish the proposed speed limit, according to the agenda item. The item will go before the City Council for final approval.
