That bridge we never called 'Dickmann' is now called 'Clay.'

Two downtown interstates identified in new report as congestion zones.

Timeline of Poplar Street Bridge project

1990 • Discussions begin between Missouri and Illinois on how to solve congestion problems downtown.

1991 • An environment investment study starts.

1997 • That study determines that the Poplar Street Bridge is a key problem, largely due to three interstates crossing the river on one bridge. Officials recommend building a new bridge over the Mississippi and relocating Interstate 70 from the Poplar Street Bridge to the new bridge.

2001-2008 • Efforts to find a way to pay for a new, $2 billion, eight-lane bridge fail. Instead, a phased approach involving a new four-lane bridge is agreed upon.

2010 • Construction begins on the new Interstate 70 bridge, which now known as the Stan Musial Veterans Memorial Bridge.

2012 • Plans begin to to rebuild the Poplar Street Bridge that call for dual ramps from northbound Interstate 55, but problems arise with an idea to eliminate Interstate 70 ramps, and that portion of the project is scrapped.

2013 • East-West Gateway hires a consultant to look at the Poplar Street Bridge. Solution proposed involves widening the bridge and adding an additional eastbound lane, as well as making dual Interstate 55 ramps from the bridge.

2014-2015 • The westbound lanes of the Poplar Street Bridge are rebuilt.

2017 • Construction is set to begin on the eastbound lanes.
