COLUMBIA — The first diverging diamond interchange in central Missouri is set to open Oct. 14 after several months of work on a roadway improvement project.
The new interchange allows vehicles to cross into opposite lanes of traffic, so cars moving through the interchange can freely make left turns onto I-70 access ramps without waiting for oncoming traffic to pass.
This MoDOT video illustrates how the diverging diamond interchange works.
The interchange is part of a $12.8 million construction project on I-70 and Stadium Boulevard. Construction began in the spring of 2013.
The bridge at Stadium Boulevard and I-70 will be closed starting next Friday at 7 p.m. It will re-open Monday, Oct. 14 at 6 a.m. During that time construction crews will be finishing the last details of the project.
"We will have a few more things to do, such as striping, get signing, and making sure the lights are all operating and working," Schupp said.
MoDOT chose a weekend when the Tigers played an away game to finish their work.
"Traffic (during a home game) would be bad enough without us working on construction," Schupp said.
Travelers will still be able to use the interstate while the bridge is closed, however they will only be able to turn right onto the exit and entrance ramps.
"Traffic will be able to get on and off," Schupp said. "The bridge overpass will just be closed."
Other parts of the project include widening the lanes of Stadium Boulevard between Broadway and the Interstate and widening Bernadette Drive between Knipp Street and Beverly drive. These remaining improvements are set to be completed by winter 2014, Schupp said.
