SIKESTON-Construction of the diverging diamond interchange at Interstate 55 and U.S. Route 61 (mile marker 99) between Cape Girardeau and Jackson, Missouri, is underway. Median crossovers will soon be in place to allow head-to-head traffic on I-55 and Route 61.
Weather permitting, the following traffic impacts will begin the week of April 6:
- Tuesday, April 7-Interstate 55: Southbound I-55 traffic will be shifted to utilize the northbound I-55 lanes in the vicinity of the Exit 99 interchange. A 10-foot width restriction will be in place.
- Tuesday, April 7-Exit 99 Interchange Ramps: The Exit 99 northbound I-55 on ramp and southbound I-55 off ramp will be closed to traffic.
- Thursday, April 9-Route 61: Northbound Route 61 traffic will be shifted to utilize southbound Route 61. An 11-foot width restriction will be in place.
During this phase of construction, contractor crews will replace the southbound I-55 bridge. Completion of the southbound bridge is anticipated in Dec. 2020. In early 2021, work will begin to replace the northbound bridge.
The work zones will be marked with signs. Motorists are urged to use extreme caution while traveling near the area.
