A new interchange will be built at I-275 and Graves Rd. Specifically, these improvements will:
Provide a new double crossover diamond (DCD) interchange at I-275 and Graves Rd. This innovative solution has been growing in popularity because it supports safer traffic movements by eliminating left turns made against oncoming traffic. The new interchange will allow for on and off access to and from I-275 at Graves Rd.
Extend the third westbound lane on I-275 past Graves Rd.
Build an additional travel lane on eastbound I-275 between Graves Rd. and KY 237
Widen and realign Graves Rd. to avoid historic farmland and minimize the impact to local streams
Shift the intersection of Williams Rd. and Graves Rd. away from the new ramps
Improve the intersection at Graves Rd. and KY 20
Make safety enhancements at the KY 237/Hebron interchange
Provide sidewalks along Graves Rd. from KY 20 to KY 237
are these improvements taking place?
The purpose of the Graves Rd. Interchange Project is to improve mobility and safety in this rapidly-growing area in northern Boone County.
The existing KY 237 interchange with I-275 (Exit #8) is experiencing substantial traffic congestion, including traffic backing-up onto mainline I-275 at the KY 237 westbound off-ramp. The surrounding area is expected to see continued traffic growth as a result of changes at the Cincinnati/Northern Kentucky International Airport and the associated business and industrial facilities. Additionally, residential developments north and south of I-275 continue to add to the demand on the surrounding roadway network.
The outside lane of both I-275 east and westbound from just west of the KY 237 interchange to the existing Graves Rd. bridge will be closed Thursday and Friday nights at 8 p.m., until 6 a.m., the following morning, so that crews can set-up barrier wall to begin initial work for construction of a full movement interchange at I-275 and Graves Rd.
Major construction activity and lane impacts will not begin until 2020.
much will the project cost?
Design, utility relocation and construction will be completed under one comprehensive $56 million contract.
