Interstate 70 westbound will be closed at the Brownstown exit this morning. The closure will last for 2 or 3 hours. Westbound traffic will be getting off at the Brownstown exit (mile marker 68) and then would travel west on U.S. Route 40 to Vandalia, then north onto U.S. Route 51 and then back on the interstate at Vandalia/Pana exit (mile marker 63). So, during this time, it will lead to much heavier traffic on Routes 40 & 51. The closure is to repair the concrete divider that was recently hit by a semi.
