Lee’s Summit & Independence drivers should expect delays when I-470 bridge work begins

INDEPENDENCE, Mo. -- Rainy weather delayed preparations for a major road project over the weekend, but road crews will soon be shutting down lanes in a busy part of the metro, causing backups of more than an hour.

This is the end of a project that started last fall: 15 bridges on Interstate 470 from the Three Trails Crossing to Interstate 70 all being rehabbed.

It's already caused countless headaches for drivers who use this artery to get to home or work. Now, it's about to get a lot worse.

Road crews will soon reduce I-470 to one lane in both directions as they fix the bridges at I-70, 40 Highway and those that span the Little Blue River.

But before crews can begin this project, they must pave lanes for a detour. The weekend rain delayed this part of the project and ultimately pushed that start of the bridge work back.

Now, MoDOT crews have rescheduled the paving work. It's slated to begin at 8 p.m. Friday until 5 a.m. Monday. The major bridge rehab is slated to start mid-August, but MoDOT said that could change if delays arise.

More than 60,000 cars use I-470 to go through this intersection every day, so MoDOT warns backups could lead to 75-minute delays.

These bridges were built in the 1960s, so they are old. Instead of replacing them, MoDOT is repairing them to give them 15 to 20 more years of life.
