Northbound I-35 into downtown Kansas City is starting to come unclogged as highway crews repair a broken expansion joint in the road.
The Missouri Department of Transportation announced early this afternoon that a second lane of northbound traffic re-opened just before the ramp to Broadway at the north end of the Southwest Trafficway Bridge.
The highway had been down to one lane since this morning when the expansion joint popped out of the road, leaving a giant pot hole in its place.
Repairs were needed because a steel expansion joint that connects two portions of the bridge became dislodged about 2:30 a.m. Tuesday. Crews had to restrict traffic to the far left lane.
Traffic was already restricted to two narrow lanes along I-35, from Cambridge Circle to north of West Pennway as part of a project to re-deck and rehabilitate more than a dozen bridges in and around the downtown loop.
Traffic was backed up during the morning’s rush hour. At 9 a.m., traffic was still moving slowly as far back as Lamar Avenue.
Speeds along I-35 from the 18th Street Expressway into downtown were slower than 30 mph.
