Crews have progressed as scheduled with the two local Missouri Department of Transportation bridge projects – repairing three pairs of bridges on Interstate 470 and constructing three new ones over Interstate 70 – the department says.

The repairs for the I-470 bridges over U.S. 40 and the Little Blue River are half-complete, as workers shifted the single lane for traffic earlier this week.

That has not yet happened with the bridges over I-70, where more extensive work is required and the loop ramps have all been closed for a couple weeks.

“We've known all along this would take a little longer,” Lairyn McGregor, MoDOT spokesperson, said of the bridges over I-70. “Once they along more on 70 they will open up some of the loops.”

All the I-470 work should be finished in mid-October, she said, though MoDOT initially had alerted motorists that closures could last through the month if weather delays occurred.

As for the new bridges for Phelps Road, Crysler Avenue and Pittman Road over I-70, those are all on track to be completed by December. MoDOT closed that stretch of I-70 one weekend in the spring to demolish the bridges, and the department has also closed the eastbound I-70 entrance ramp from Blue Ridge Boulevard for the duration of project to ease potential congestion at the Crysler construction area. The side walls and buried supports for all three new bridges are up.

In addition, MoDOT's project in Oak Grove – making the I-70 overpass a diverging diamond – is scheduled for completion this fall.
