Why were 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 old 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.
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.
