The construction of a new interchange off I-77 at CR 80 in Dover is intended to help relieve congestion at the existing I-77 interchanges in Dover and Strasburg. This interchange will provide improved access to the rapidly developing area in north Dover and better access for commercial traffic due to current truck traffic restrictions. In addition to a new diamond interchange, the project will include the reconstruction of 0.7 mile of CR 80, the construction of a new overpass over I-77, the replacement of a bridge over the Sugar Creek, and the relocation of a portion of Progress Street. 

The construction for the new interchange on I-77 at CR 80 will be separated into three parts. The first part will include the reconstruction of CR 80 from the west end of the project to the RJ Corman railroad tracks. The second part will consist of the reconstruction of CR 80 (Ohio Avenue) from the railroad tracks to Wooster Avenue and the construction of relocated Progress Street. The third part will include the construction of the four interchange ramps.

Traffic will be maintained at all times except for the period of time that will be required to construct Part One. It includes a new bridge over I-77, widening the bridge over the Sugar Creek, and new roadway. The road must be closed due to the type of structure being built and the difference in elevation between the existing roadway and the proposed roadway. The new bridge over I-77 will be approximately four feet higher than the existing bridge.

The contractor may choose to perform the construction of these parts separately or at one time but will be required to follow the indicated phasing as shown with each part of construction.
