Due to recent traffic incidents in the area, Grapevine police officers are cracking down on speeding motorists driving southbound on SH 121 North near the exit to the Dallas-Fort Worth International Airport, according to the Grapevine Police Department’s social media pages.

The posted speed limit for that section of SH 121 is 55 miles per hour to accommodate construction work taking place in the area. The police department reported at least four multi-vehicle crashes since the end of December, according to an announcement it made on Facebook.

To reduce the risk of crashes, officers will begin stricter enforcement of the speed limit by issuing more tickets to violators. Because it is in a construction zone, traffic fines are also doubled.
