About the project

The project is designed to reconstruct the bridge carrying State Route 37/State Route 661 over State Route 16 in Granville. The project will also include turn lane additions along the SR 37/SR 661 entrance and exit ramps. The intersection of SR 661 and River Road/Weaver Drive will be improved to include turn lanes along SR 37/SR Route 661 and along westbound River Road. The intersection will be signalized. 

The $9 million project is expected to begin in spring 2020 and completed in fall 2021.

Expected impacts to traffic

Construction began in Spring 2020 and will be undertaken in two phases. Construction schedule is subject to change.

Current Traffic Pattern

The northbound traffic on SR 37/SR 661 remains on the current routing; southbound traffic will be detoured to the adjacent interchange, west of the project, via Weaver Drive to SR16/Columbus Road/Cherry Street to Granview Road to Silver Street. The bridge will be closed to southbound traffic. SR 16EB/WB traffic wishing to travel to the SR 37/661 interchange will exit SR 16 at the adjacent interchange to the west. All ramps at the interchange are closed with the exception of the SR 16 eastbound on-ramp.

2021 Construction Season

Spring 2021:

  • SR 37 NB will be open over the old bridge while bridge parapet and vandal fence on the west side are constructed.  SR 661 SB traffic will follow the marked detour.
  • SR 37 NB will be moved to the new (west) side of the bridge while the east side of the road is widened.  SR661 SB traffic will follow the marked detour. The ramp to SR 16 WB will be open to NB traffic.  The remaining ramps will be closed.  However, the ramp to SR 16 EB will be open to emergency traffic only.
  • SR 661/37 NB and SB traffic will travel on the new side of the bridge
  • Entrance to SR 16 WB from SR 661 will be open to SR 661 SB traffic only
  • Exit to SR 661 from SR 16 WB will be open to SR 661 NB traffic only
  • Exit from SR 16 EB to SR 661 will be open to SR 37 EB traffic only
  • The entrance ramp to SR 16 EB from SR 661 will be open to all SR 37 WB traffic and only to emergency personnel travelling on SR 37 EB
  • River Road will close for 21 days to WB traffic. This closure will be at SR 661 and extend approximately 500 feet to the west. EB and WB traffic will be able to travel in both directions from SR 16 to the west side of the closure. WB River Road traffic wishing to get to SR 661 will need to follow SR 16 WB and exit at the next interchange and follow Weaver Drive EB back to SR 661. This closure is tentatively set for April 2021.

Fall 2021:

  • The SR 37/661 bridge and all ramps are expected to be open
  • River Road will close at SR 16 at the end of the project. River Rd will end in a cul-de-sac and will no longer be able to access SR 16.

Spring 2022:

  • Remaining  roadway work on SR 37/661 to be completed. Some short term lane closures should be expected during this time.
  • River Road will close at SR 16 at the end of the project. River Rd will end in a cul-de-sac and will no longer be able to access SR 16.
