ST. LOUIS (KTVI) - Work crews with the Missouri Department of Transportation will tear down the Grand Avenue bridge over Interstate 44 this weekend. As a result, both directions of I-44 between Jefferson and Vandeventer will close, beginning Friday night at 8 p.m.

Grand Avenue in both directions will also close at 7 p.m. Friday. On Thursday evening, commuter Megan O'Laughlin-Nordheim was getting gas at the BP Station at Grand and Blaine, just north of I-44.

“It's kind of a mess right now,” said O’Laughlin-Nordheim. “We just take 39th as much as we can to avoid it. It just takes a little bit longer, but it's better than sitting in traffic on Grand.”

Terrell Moore uses the nearby bus stop on Grand to get to work downtown.

“As of right now, I'm on a bus,” he said. “I catch buses and Metrolink for my job at the Missouri Athletic Club. It's going to inconvenience some of my professors at UMSL or Washington University. It's really going to affect a lot of workers in my neighborhood.”

On I-55 at Reavis Barracks, two lanes of traffic each way closed Wednesday night. Thursday morning, all three lanes of traffic were shifted to the right side of the work zone.

Further west, at I-44 at Highway 141, MoDOT will break ground at 10 a.m. Friday for upcoming traffic and drainage improvements at that intersection.
