CARMEL – Two new roundabouts are coming to Carmel.

The new roundabouts will be at 116th Street and College Avenue, and 116th Street and Guilford Road. Construction for the new roundabouts will begin July 15.

The two projects will be built simultaneously and will require lane restrictions, but traffic won’t be closed.

Construction costs will be about $3.4 million, with 80% of that coming from federal funding in the form of a Congestion Mitigation and Air Quality Improvement grant. Most of the work will be completed in 125 days, according to the city of Carmel.

The construction schedule is as follows:

· Phase 1 (approximately 4-10 days): Preliminary work will take place within the median of 116th Street to allow traffic shifts in future phases.

· Phase 2 (approximately 35 days): The northern portion of both roundabouts will be constructed. There will be full vehicle access to the south, but no vehicle access to the north at Guilford Road or College Avenue. Both east and west traffic will be maintained (one lane in each direction) on the southern portion of the intersections on 116th Street.

· Phase 3 (approximately 35 days): The southern portion of both roundabouts will be constructed. East and west vehicular traffic will be maintained on the northern portion of the intersections on 116th Street during this phase. There will be full vehicle access to the north, but no vehicle access to the south at Guilford Road or College Avenue.

· Phase 4 (approximately 30 days): During phase four, there will be full access from the north and the south to 116th Street at both roundabouts but east-west access across the roundabouts will not be available as work in the center of the roundabouts is completed.

· Phase 5 (approximately 15 days): Both intersections will be substantially complete with finishing work taking place during this time. Temporary lane restrictions are possible during this time in order to complete median work along with final asphalt surface and pavement markings.
