Oliver Road Intersection Improvement Project



Project Overview

The Oliver Road Intersection Improvement Project includes the construction of a five-leg roundabout at the intersections of Oliver (Route 4008), Flower, and Hamot (Route 4010) roads in Summit Township, Erie County. 

The intersection safety improvement project was created to address concerns raised by data gathered from 2012 to 2016 and studies conducted in 2019, which showed that crash rates at this intersection were over two times the statewide average for similar roadways and that the intersection geometry contributed to a large percentage of these crashes.

The two-year project includes removal of the existing intersections and construction of roundabout. Additional work includes milling and paving intersecting roads, construction of sidewalks, ADA curb ramps, drainage improvements, environmental mitigation, lighting, vegetation replacement, and pavement markings. Work will be done in seven phases and various detours will be in place during those phases.

In 2021, work was done offline of the current intersection. This included new alignments of Flower and the north portion of Hamot Road, new roadway approaches, drainage, sidewalks, highway lighting and concrete islands.

Work in 2022 will start with Phase 1B . Various detours will be needed throughout the summer. See the phases below for details on each anticipated detour.

The roundabout is expected to be fully opened to traffic in October 2022.

Project Phases

Phase 1A - COMPLETED
Will include the construction of the offline portion of the roundabout and the offline portion of the new alignments of Flower and Hamot roads. Work also includes new roadway approaches, drainage, sidewalks, and concrete islands. Work is expected to be completed in the 2021 construction season.

Phase 1B - COMPLETED
Will focus on the Hamot Road north approach to the new roadway and the removal of the unused portion of Hamot Road. Temporary lanes will be constructed for two-lane traffic on Hamot Road. Additional drainage work will also be done. Traffic on Hamot Road will be detoured using Route 19 (Peach Street) and Hershey Road.  The detour is expected to be in place May 10. Work is expected to take approximately eight to nine days.

Phase 2A - COMPLETED
Will include the construction of the approach on Oliver Road, as well as drainage, sidewalks, and concrete islands. Traffic will use the temporary lanes on Hamot Road. Work is expected to take approximately 12 days to complete.

Phase 2B - COMPLETED
Will include the tie-in between Oliver Road approach and the new roadway. Work will also include the removal of a portion of the existing Oliver Road as well as drainage and sidewalks. Oliver Road traffic will be detoured using Hamot Road, Hershey Road, and Route 19. Work is expected to take approximately 11 days.DJI_0017.JPG

Phase 3 - COMPLETED
Will include the construction of the tie-in between Flower Road approach and new roadway. Work will also include the removal of a portion of the existing Flower Road as well as drainage and sidewalks. Flower Road traffic will be detoured using the Oliver Road, Dunn Valley Road (Route 4013), and Reichert Road (Route 4013). Work is expected to take approximately 15 days. 

Phase 4 - COMPLETED
Work will include removing another portion of the existing Oliver Road approach and construction of the tie-in between the Oliver Road and the new roadway. Traffic on Oliver Road and Hamot Road will be detoured using Flower Road, Reichert Road, and Dunn Valley Road. Work is expected to take approximately 13 days.

Phase 5 - COMPLETED
Will include constructing a tie-in between the south Hamot Road approach and the new roadway. Work will require varying detours between Oliver Road and Hamot Road.  Drivers should be alert for changing traffic patterns and detour signs. Work is expected to take approximately 10 days to complete. 

Phase 6
Will include constructing the central island including the truck apron, curbs and landscaping. Work is expected to take approximately 28 days to complete. 

Phase 7
Will include milling and paving the final surface for the roundabout lanes, as well as sign installation.

Project Updates

9-19-22

Work at the Oliver Road Roundabout in Summit Township, Erie County will head into the last phase soon as final layer of paving starts the week of September 26, 2022. It is expected to take approximately two weeks to complete the paving, weather permitting.

During that time, portions of Oliver (Route 4008), Hamot (Route 4010), and Flower roads will have to be closed. Motorists are advised to be alert for traffic pattern changes near the intersection and to follow detours signs, as they will be changing as the paving and line painting progresses.

Once the paving is complete, the single-lane, five-leg roundabout will be fully opened to all traffic though additional work will be done off road, including signs, sidewalks, drainage, landscaping and lighting. The project is expected to be completed in October 2022.
