Traffic on Interstate 70 and the Route BB interchange (Exit 115) in Boone County will be impacted the weekend of June 16-19 as westbound I-70 traffic is moved onto the new Lance Corporal Leon Deraps I-70 Missouri River Bridge at Rocheport.

This will be the first traffic to use the new westbound bridge constructed as part of the Rocheport Bridge project.

The Route BB bridge over I-70 will also be demolished over this weekend, for reconstruction.

The shifting of westbound I-70 traffic to the new bridge and the demolition of the Route BB overpass will require the around-the-clock narrowing of I-70 to one lane and rerouting of I-70 traffic at Exit 115 from 7 p.m. Friday, June 16, through 5 a.m. Monday, June 19. Motorists should expect delays.

The detailed traffic impacts on both I-70 and Route BB are as follows:
I-70 impacts June 16 – 19:
-Eastbound I-70 will narrow to one lane as traffic crosses and exits the existing Rocheport Bridge. Drivers will then be directed up and over the ramps at Exit 115 and back onto I-70 eastbound into two lanes.
-Westbound I-70 will be narrowed to one lane as travelers approach Exit 115. Motorists will go over the on/off ramps and continue onto the newly constructed westbound Rocheport Bridge, where they will be able to use both lanes.

Route BB bridge replacement impacts, June 16 – late October:
-Eastbound traffic on I-70 will not be able to use Exit 115 to access Route BB.
-Route BB traffic will not be able to access eastbound I-70 at the overpass.
-A signed detour will be in place over Spur 240, U.S. Route 40 and Route J (Exit 117).

All projects are weather permitting, and schedules are subject to change.
