ST. CHARLES, MO (KTVI) - There is going be quite a 'boom' Tuesday morning in St. Charles.  MoDOT crews are slated to blast basically the rest of the Blanchette Bridge on the closed westbound side.

Because of the low cloud cover, MoDOT says people in the area should not be surprised when they hear the "boom" because the clouds will keep that sound close to the ground.

The blast means there could be some significant traffic delays.

The blast on the shutdown part of the bridge is scheduled to take place around 10:15am this morning.

But lanes will begin to be closed more than an hour earlier.

MoDOT is strongly advising drivers to avoid I-70 in the Blanchette Bridge area between 9am and 11am this morning.

At nine this morning... MoDOT is planning to shut down one lane of I-70 in both directions between I-270 and Route 94.

Then at 10am, I-70 is scheduled to be completely shut down in both directions in that same area.

I-70 traffic during that period will be rerouted onto the page extension and route 370.

After the blast, MoDOT will have to sweep the lanes on the eastbound side of the bridge make sure they are clear of any debris before reopening them.

Four a half million pounds of steel will drop into the Missouri River from the blast.

About 1,000 feet of the old bridge is scheduled to come down.

That`s substantially more than the 350 feet of bridge that fell into the river after the first section of the shutdown bridge was blasted last month.

MoDOT tells me this morning that at this point the blast is still a go even with the rain during these early hours.

If it`s still raining at 10am, MoDOT says the blast could be delayed a few minutes or possibly postponed until tomorrow.
