North and Southbound I-55 To Open At Center Junction-Diverging Diamond In Cape County

On Thurs. Sept. 30. construction of the diverging diamond interchange at Interstate 55 and U.S. Route 61--mile marker 99--between Cape Girardeau and Jackson, Missouri, will continue. 

A traffic flow shift will begin during the morning rush hour, and traffic will divert to one lane in each direction. 

All interstate ramps will be open to right turn movements only. Route 61 and Kingshighway traffic will not be impacted.

Following the traffic shift, contractor crews will begin removing the median crossovers and completing pavement repairs south of the southbound I-55 bridge. The northbound I-55 bridge is nearing completion.

Drivers and motorists are urged to proceed with caution in the marked work zones.



The diverging diamond project at Center Junction, between Cape Girardeau and Jackson began in Feb. 2020, after a public meeting on the major road construction project in Aug. 2018. 


The $17.4 million dollar project was awarded to Penzel Construction Co., Inc., in Jan. 2020. It included the construction of a diverging diamond interchange and replacement of two I-55 bridges at the junction of I-55 and Route 61, in the North Kingshighway and Jackson Boulevard portion, in Cape Girardeau, County.



According to MODOT's website, the projected completion date is Nov. 2021.
