Starting Monday, May 21st, the Rock Island Arsenal Exit Ramp to River Drive will be limited to a west bound right turn only onto River Drive. Motorists will not be allowed to turn east bound onto River Drive. Motorists should follow the posted detour for access to the I-74 Bridge using the 14th Street Exit. The detour is scheduled to be in effect for one week while work is completed on River Drive underneath the Arsenal Overpass. The Rock Island Arsenal Entrance Ramp at River Drive will remain open during the construction as will River Drive.
