Dennis Corporation Teams With 3M to Target Deadly Intersections

3M LogoDennis Corporation’s teaming with 3M on Statewide Intersection Improvements for SCDOT was recently recognized in an article titled, “States Search for Ways to Cut Traffic Death. As a team, 3M and Dennis Corporation installed larger signs, new pavement markings, and traffic signal lights that have already shown to reduce the amount of overall crashes at these intersections.

For the project, Dennis Corporation provided sub-contractor oversight for pavement marking and installation of traffic signs on behalf of 3M. Dennis Corporation also maintained and reconciled daily production results, performed quality inspections, took measurements and reported product installation, and recorded and maintained inventory and consumption records of 3M materials located at remote sites supporting product installation.

The project’s success has garnered attention from transportation experts. “The preliminary results appear to show that those relatively simply fixes are having a big impact. An early analysis of 458 of the intersections that were modified found a 22 percent reduction in crashes overall,” according to Jenni Bergal in her article, “States Search for Ways to Cut Traffic Deaths.”
