I-64 Double Deck Rehabilitation Project

What is the latest on this project?

Work continues on this project through the end of 2012. MoDOT is working with the various downtown attractions (Busch Stadium, Peabody, Edward Jones Dome, ScottTrade, etc.) to ensure traffic can get through for events. Driver can still expect morning lane closures on eastbound I-64 for safety.

MoDOT updates schedule for I-64 double deck work downtown (October 3)

Work continues on the westbound bridge's driving surface. Even though barrier is removed from the roadway, MoDOT still closes up to two lanes during non-peak traffic (morning rush) on westbound I-64. All lanes on westbound I-64 at the double deck are open between 5 a.m. and 10 a.m. weekdays.

Work on westbound I-64 required a number of full weekend closures of the westbound interstate to complete. Westbound weekend closures are currently complete.

Work has begun on eastbound I-64 and continues through the remainder of the year. For safety, both the Forest Park and the Pine Street ramps to eastbound I-64 will be closed until mid-December. Up to two lanes may be closed on eastbound I-64 during non-peak traffic (evening rush). All lanes on eastbound I-64 are open between 2 p.m. and 8 pm. weekdays.

Currently, the schedule calls for the following weekend closures of I-64. All weekend full closures of the interstate have been completed.

Why are Improvements Needed on I-64's Double Deck Bridge from 21st Street to the Poplar Street Bridge?

The I-64 double deck approach to the Poplar Street Bridge extends from 21st Street to the bridge. This structure is in a double deck configuration from approximately 14th Street to Broadway. The bridge was opened to traffic in November 1967 and is over 43 years old. The double deck needs to be rehabilitated to ensure a longer lifespan. The expansion joints in between the bridge decks also need to be replaced because they are in poor condition due to age.

Below are links to photos of the current driving surface of the I-64 double deck bridge:

What Improvements Will MoDOT Accomplish?

Repair the driving surface lanes and put a new concrete surface on it to gain a longer year lifespan up to approximately 25 years.
Replace 37 expansion joints.
Repair remaining drainage structures on and below the bridge decks.

How Will Traffic Be Impacted?

Traffic will be impacted by various lane closures on weekdays and weekends while crews repair the I-64 double deck bridge. Interstate 64 will be fully closed for several weekends while the work is occurring between 21st Street and the Poplar Street Bridge.

Detour Routes

Motorists can use I-70 and I-55/I-44 as alternate routes to and from downtown St. Louis. Motorists can also use Jefferson Barracks Bridge and Chain of Rocks Bridge, along with other bridge crossings in the downtown area, such as the Martin Luther King, Eads and McKinley bridges.
