MoDOT to start major project on I-64 double deck downtown

ST. LOUIS - The Missouri Department of Transportation has begun work on a major project on the I-64 double deck structure in downtown St. Louis that will have major impacts on traffic until the end of the year.

The project will require permanent lane closures on the bridge and several weekend interstate closures throughout 2012, including a closure of westbound I-64 this weekend, starting at 8:30 p.m. Friday, April 27. The interstate will reopen by 9 a.m. Sunday, April 29.  This work is weather permitting.  The department will open one lane of westbound I-64 on Saturday, April 28 at 10 a.m. to allow for baseball traffic to enter into downtown.  

In addition, the ramp from Broadway to westbound I-64 closes April 27 until October.  Drivers can use the 10th Street and 14th Street ramps to access the I-64 westbound.

One lane will be closed, around the clock, on westbound I-64 from April 29th to late August.  During non-peak hours, crews will have two of the three lanes closed. Work on westbound I-64 will require approximately 10 full weekend closures of the westbound interstate to complete.

Work begins on eastbound I-64 in late August and continues through late October. It will also require a full lane closure, around the clock on eastbound I-64.  During non-peak hours, crews will have two of the three lanes closed.   Work on eastbound I-64 will also require approximately three full interstate closures. 

This work is to remove and replace the driving surface on the double deck portion of I-64 and to replace the deteriorated joints.

"The double deck is more than 50 years old, and this is part of the preventative maintenance work needed to extend its useful life another 25 years. Our previous jobs over the last ten years on the double deck were to seismically retrofit the structure.  Part of this work required us to cut holes in the deck and add additional steel and re-pour the deck in hundreds of locations.  Since, this job is now complete, we need a new driving surface to smooth out the ride for motorists and preserve the deck for the future," said Deanna Venker, MoDOT Area Engineer for St. Louis City.

"We understand that this is going to be challenging for morning and evening commuters, and for people who attend downtown events at Busch Stadium. We have a very aggressive schedule with our contractor, so we can complete this project as quickly as possible," she said.
