Beginning as early as May 27, contractor crews are scheduled to install bridge girders on the new Routes E/Y bridge over Interstate 70 in Montgomery County, at Exit 183 in Jonesburg.

To facilitate this work, eastbound and westbound I-70 traffic will utilize the I-70 on/off ramps at the interchange of Routes E and Y.

Weather permitting, girder installation work will tentatively occur between 8 p.m. on Wednesday, May 27 and the morning hours of Thursday, May 28. During this time, traffic impacts will include:

• Eastbound and westbound I-70 will be reduced to one lane with an 11-foot width restriction in place, and all traffic will be diverted up and over the interchange ramps, then back to I-70.
  • Eastbound I-70: work will begin at 8 p.m. on Wednesday, May 27 and tentatively reopen to traffic by 4 a.m., just in time for morning traffic on Thursday, May 28.
  •  
  • Westbound I-70: operations are anticipated to begin in the westbound direction by 10:30 p.m. on Wednesday, May 27 and reopen during the morning hours of Thursday, May 28.
  • No turning movements will be allowed at the interchange ramp terminals, thereby eliminating access to the outer service roads and Routes E/Y.
  • Delays on I-70 are expected during the temporary closures. To alleviate congestion, motorists are strongly advised to avoid the area and use alternate routes.

• Additionally, a temporary closure of Routes E/Y will be in place:
  • Route E will close between the interchange ramps and Northwest Service Road.
  • Route Y will close just south of the eastbound I-70 ramp terminal.
• To access I-70, local traffic will utilize the signed detours to the neighboring interchanges at Route F located at Exit 179 at High Hill or Routes A/B at Exit 188, near Pendleton.
  • Route E (eastbound/westbound) - utilize the Northwest Service Road to Route F interchange at High Hill (west) or Routes A/B interchange, near Pendleton (east)
  • Route Y (eastbound) - take Veteran’s Memorial Parkway to the Route A/B interchange
  • Route Y (westbound) - travel west on Route Y to Route Y Spur/Fleahman Road, crossing to the north side of I-70, then turn left onto the Northwest Service Road to reach the Route F Interchange

Once the bridge girder installation is complete, I-70 traffic will return to its normal configuration, and Routes E and Y will regain access to all interchange ramps. However, the bridge will remain closed until construction is complete, and detours will stay in place through summer 2026.

Signs and message boards will be in place to alert motorists, as schedule changes occur. MoDOT will alert the public about the project through signs, news releases and social media. As the project moves forward, additional information will be available on the project website at https://www.modot.org/projects/route-e-and-route-y-bridge-replacement-over-interstate-70-montgomery-county

Emery Sapp & Sons, Inc. was awarded the contract last year in the amount of $13.7M. This project is tentatively scheduled to be completed by late summer of 2026.

Included in this contract is an additional bridge rehabilitation project, located on Route A/B over I-70 near Pendleton in Warren County. This project began in the spring of 2025 and was completed last fall.
