Seal Coating in Minneapolis: Caution to Bicyclists

Filed Under green, transit 

City of Minneapolis Public Works crews are currently seal coating streets all over town. Seal coating involves applying a layer of tar emulsion followed by rocks. Immediately following the seal coat application (which takes only a short while), motor vehicles are allowed to drive on the new surface. The pressure of vehicle tires pushes the rock down into the tar. City crews return about a week after application to sweep the street, followed by repainting. Seal coating is done to help extend the life of the road surface. The general rule is that new pavement gets seal coated one year after installation and then on a seven-year cycle, with two to three seal coats for the life of the pavement. Seal coating can present some difficulties for bicyclists and pedestrians. The loose gravel applied on top of the tar can be difficult to traverse. We encourage bicycles to pay close attention to the orange “Loose Gravel” signs that appear on the block before a seal coat starts. You may also encounter seal coats when crossing intersections at some streets. The general rule is to stay alert and be prepared to slow or stop if necessary. Pedestrians walking along seal coated streets should expect some dust and may find that crosswalks are covered in loose gravel. Seal coat application is scheduled to conclude by the second week in August, with sweeping and painting several weeks later. Additional information about the seal coat program (including a map and schedule) can be found on the City of Minneapolis website: http://www.minneapolismn.gov/cip/all/WCMS1P-085418 Thank you for your patience during the summer construction season, City of Minneapolis Bicycle and Pedestrian Section
