Not the whole thing, just a small part. This is temporary, part of the replacement of both bridges over the creek just north of Brand Rd.. Here is an email from the City detailing it:
Muirfield Drive Bridge Replacement
Crews are working in the Muirfield area to replace the existing vehicular bridges on Muirfield Drive just north of Brand Road.
Drivers should expect temporary lane closures on Muirfield Drive between Brand Road and Moors Place North. Two-way traffic will be maintained.
Beginning Monday, June 14, 2021, the shared use path on the east side of Muirfield Drive will be closed between Brand Road and Muirfield Green Boulevard. The detour for pedestrians and bicyclists will be to use the Brand Road roundabout to the Muirfield Drive shared use path on the west side of Muirfield Drive to the Tartan Drive pedestrian tunnel. The path on the west side of the road will remain open for the first phase of construction, but closures will be implemented and communicated as needed.
Various traffic impacts are scheduled throughout this project. Updates will be shared on this webpage: https://dublinohiousa.gov/newsroom/muirfield-bridge-work
