An overnight road closure will begin Tuesday night in LaSalle. The closure will be at the Sandwich West Parkway and Heritage Drive roundabout. Work will take place from 10 p.m. to 6 a.m., weather dependent, until Friday. This is to finish line painting and concrete repairs. The town is doing the construction at night in an effort to reduce traffic impacts. Drivers are asked to use other routes while the work is taking place. Detour signs will be put up.
