HAMILTON COUNTY – This weekend, crews plan to shift #US31 between 146th and 161st streets into a final configuration and open new ramps in the “split diamond” interchange connecting the highway with 146th Street, 151st Street and Greyhound Pass.
Weather permitting, Rieth-Riley Construction anticipates shifting northbound U.S. 31 onto new pavement between 146th and 161st streets and opening two ramp segments beginning Saturday:
• A new northbound U.S. 31 exit ramp to 151st Street will split from the 146th Street exit.
• A new entrance ramp will open from 151st Street to northbound U.S. 31.
The existing right turn from northbound U.S. 31 to Greyhound Pass will no longer be available. This change in access is permanent. Posted and dynamic message signs will be used to help direct motorists who might be unaware of these changes:
• Northbound U.S. 31 traffic must exit south of 146th Street to access Greyhound Pass and 151st Street.
• Northbound Keystone Parkway must exit to 146th Street to access Greyhound Pass.
For a short time on Saturday, access to northbound U.S. 31 will not be available from either the signal at Greyhound Pass or the new entrance ramp from 151st Street. Motorists will be directed to use a temporary detour route following 151st Street to Oak Street and then to 161st Street.
Motorists are encouraged to be patient in this area this weekend. Various restrictions and delays should be expected as contractors work to open the ramps and implement the final traffic configuration. Motorists should remain alert and drive cautiously as the area will remain an active work zone.
Look close. You'll find bridge inspectors "looking close."
