Officials at the Indiana Department of Transportation announced Thursday the U.S. 231 edge and center line rumble strips project has been awarded to Gridlock Traffic Systems for $478,750.
The rumble strips will be installed on U.S. 231 from the two lane section of roadway north of Interstate 74 in Montgomery County to the beginning of the four lane section of roadway in southern Tippecanoe County.
Professor Darcy Bullock and his colleagues in the Joint Transportation Research Program have collaborated with INDOT on the planning and preparation of this project.
Edge line rumble strips are similar to shoulder rumble strips, but placed at the edge of the travel lane, typically in line with the edge line pavement marking. Center line rumble strips are installed at or near the center line of an undivided roadway, and may be comprised of either a single or double line of rumbles. These treatments are found to reduce run-off-road right crashes and cross center line crashes such as head-on collisions.
Rumble strips are intended to save lives and prevent serious injury by alerting drivers that they are leaving the driving lane. They consist of raised or grooved patterns on the roadway. They provide the driver with both an audible warning (rumbling sound) and a physical vibration.
Gridlock will install these during the evening hours to minimize the impact to traffic, working from 7 p.m. until 7 a.m. Some daytime weekend work may occur. Through the town of Linden and Romney the rumble strips will not be installed. Construction should begin on or after Tuesday and be completed by Oct. 31.
INDOT reminds motorists to follow the posted work zone speed limit, use caution and consider worker safety when traveling through a construction zone.
