Contractor crews will soon shift to the final stage of construction at the Routes E/Y and Interstate 70 interchange in Montgomery County, at Exit 183 in Jonesburg. In addition to completing the bridge, work will begin on the interchange ramps.

Weather permitting, as early as June 15, contractor crews will close the interchange ramps to facilitate construction on both the eastbound and westbound I-70 on and off ramps.

During this time, traffic impacts will include:

• A full closure at all four of the I-70 interchange ramps will be required for a period of up to 40 days: I-70 traffic will continue to flow uninterrupted in both the eastbound and westbound directions. A signed detour will divert eastbound and westbound I-70 ramp traffic to the Route F interchange (at Exit 179) at High Hill or the interchange at Routes A and B (located at Exit 188), near Pendleton.
• Additionally, Routes E and Y will be closed at the following locations: Route E will close at the Northwest Service Road and 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) - utilizing Northwest Service Road to Route F interchange at High Hill (west) or Routes A/B interchange, near Pendleton (east); Route Y (eastbound) - take Veterans Memorial Parkway to the Route A/B interchange; and 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.

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.
