The Rockford Road (County Road 9) bridge over Interstate 494 in Plymouth is set to close to traffic at 10 p.m. Friday, July 12. The bridge will remain closed for approximately 100 days as part of the second phase of the project.

To allow for demolition of the bridge, I-494 will be closed from Interstate 394 to Interstate 694/Interstate 94 at 10 p.m. Friday, July 12. The I-494 roadway and ramps are set to reopen by 5 a.m. Monday, July 15.

The weekend closure includes these ramps to access I-494:

Ramps closing at 9 p.m. July 12

• Westbound I-394 to northbound I-494

• Eastbound I-394 to northbound I-494

• I-394/Highway 12 to northbound I-494

• Carlson Parkway to northbound I-494

• County Road 6 to northbound I-494

• Highway 55 to northbound I-494

• Bass Lake Road to southbound I-494

Ramps closing at 10 p.m. July 12

• Westbound I-694/I-94 to southbound I-494

• Eastbound I-94 to southbound I-494

Motorists should follow the posted detour route, which includes Highway 169.

Weekend closure of Rockford/I-494 Interchange

In addition, the Rockford Road/I-494 interchange, including the ramps to access I-494, will be closed for the weekend beginning at 10 p.m. Friday, July 12, to allow for demolition of the bridge. Rockford Road will be closed between Vinewood and Annapolis/Berkshire lanes through the weekend.

Phase 2: Bridge Demolition/Reconstruction

All four ramps will be open to traffic during this phase, but motorists will not be able to cross over I-494. Motorists may turn right onto/at the top of the ramps. For example:

• To use the northbound I-494 ramp, motorists must come from the east and turn right onto the northbound I-494 ramp.

• To use the southbound I-494 ramp, motorists must come from the west and turn right onto the southbound I-494 ramp.

• To access Rockford Road east of I-494, motorists may exit northbound I-494 and turn right onto eastbound Rockford Road.

• To access Rockford Road west of I-494, motorists may exit southbound I-494 and turn right onto westbound Rockford Road.

Motorists should follow the posted detour routes during Phase 2, which include I-494, Highway 55 and Bass Lake Road. Local traffic detour route includes Highway 55, Northwest Boulevard (County Road 61) and Rockford Road.

Phase 2 may require additional night or weekend closures of I-494. After the completion of this phase, the new bridge will be open to traffic. All dates and timing of phases are weather dependent.

Project overview

The project will improve traffic flow and increase the capacity of the interchange. To best accommodate access for nearby businesses and residents traveling the affected area, the project will be completed in three phases.

In addition to replacement of the bridge, the project includes a wider bridge with dual, dedicated left turn lanes onto I-494, wider ramps with improved turn lanes onto Rockford Road and improvements for pedestrians and bicyclists.
