Graves Rd. Interchange Project

Graves Road Double Crossover Diamond Interchange Project Map


is the scope of the project?

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.


will work begin and end?


Work is expected to continue through spring 2022.

will there be impacts to traffic because of the project work?

Graves Rd. is now permanently closed to all traffic at the I-275 bridge. The closure is in place just south of Williams Rd. and just south of the I-275 bridge, which prevents traffic in either direction from crossing over the I-275 bridge. Williams Rd. remains open to traffic. 


Also, weather permitting, Monday through Friday, between 8 a.m. - 5 p.m., traffic is reduced to one lane on Graves Rd. between KY 20 (Petersburg Road) and just north of Worldwide Blvd. Traffic will be maintained by flaggers. Intermittent lane closures will continue through early June. 

Please use caution when traveling through active work zones. 


much will the project cost?

Design, utility relocation and construction will be completed under one comprehensive $56 million contract.
