Confluence Greenway--Riverfront Trail north of Downtown St. Louis

The Riverfront Trail in the vicinity of the new Mississippi River Bridge north of Downtown St. Louis has a detour route.  The detour is between Mullanphy Street and Madison Street.  The detour will be in effect while the Missouri and Illinois Departments of Transportation and its contractors construct the new Mississippi River Bridge.  A link to the location of the detour can be found here:  http://g.co/maps/5qeez

Missouri River Greenway--Highway 370 crossing over the Missouri River

The Missouri Department of Transportation (MoDOT) has closed the bicycle lane on the Route 370 Bridge, known as the Discovery Bridge.  The closure is necessary to restripe an additional lane to accommodate traffic from the closure of the westbound Interstate 70 Bridge.  The bicycle lane will remain closed until after the Interstate 70 Bridge work is complete at the end of 2013.  Route 370 will be restored back to three lanes with a bicycle lane by 2014.  

More information on the project can be found on MoDOT's website.
