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?

Saturday, Aug. 8, weather permitting:


Traffic will be shifted onto the new alignment of Williams Rd. to allow for ongoing improvement work at I-275 and Graves Rd.   


Traffic traveling southbound on Graves Rd. will come to a new four-way stop at the intersection of Graves Rd. and Worldwide Blvd., turn right on Worldwide Blvd. and then turn left onto the new alignment of Williams Rd.  


The relocation of Williams Rd. is one of several components of the I-275 & Graves Rd. project that will provide a safer and more efficient connection to the new interchange.  


Monday, Aug. 10 – Friday, Aug. 14, weather permitting:


Beginning at 8 p.m., each night, crews will begin demolition of the existing Graves Rd. bridge over I-275, which will require rolling roadblocks on I-275 eastbound and westbound.  


Significant delays are likely and drivers should seek alternate routes when possible.    

  • At 8 p.m., each night, law enforcement will be in place on I-275 eastbound just east of the Carroll Cropper bridge on the Kentucky side of the river, and will begin holding traffic in 15-minute increments. Law enforcement also will be in place at the Petersburg exit (Exit #11) and will close the on-ramp to I-275 eastbound.   

  • Following the 15-minute closure of all eastbound lanes, a 15-minute closure will begin across all westbound lanes. Law enforcement will be in place on I-275 westbound at the Airport exit (Exit #4) and will begin holding traffic in 15-minute increments. Law enforcement also will be in place at the Hebron/KY 237 exit (Exit #8) and will close the on-ramp to I-275 westbound.  


The 15-minute rolling roadblocks will continue on alternating sides of the interstate throughout the night. All lanes in both directions, as well as the access ramps to the interstate, are expected to be open to traffic by 6 a.m., the following morning.   



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. 


Please use caution when traveling through active work zones.​
