Previous updates (updated October 2015)

MoDOT was awarded a $10 million federal TIGER grant in 2014 for the new Route 47 Missouri River Bridge.  For more information on TIGER grants, go to www.dot.gov/tiger.


The Missouri Department of Transportation in partnership with the City of Washington, Franklin County and Warren County will replace the deteriorating 1936 Route 47 bridge over the Missouri River in Washington.  This effort is with the support of East West Gateway Council of Governments and Boonslick Regional Planning Commission.

This Missouri River bridge is located between Jefferson City and St. Louis.  The bridge provides a vital link between Warren County to the north and Franklin County to the south.

Below are some renderings of the new bridge:

Recommended Improvements

The preferred alternative to the existing bridge is to construct a new bridge just upstream or west of the existing structure.  The new bridge will provide two 12-foot lanes with 10-foot shoulders and a ten-foot protected bike/pedestrian path with a connection to the KATY Trail in Warren County.  Funding for the new bridge is available for construction to start in fall 2016.

Why is a new bridge needed?

The Route 47 Missouri River Bridge needs to be replaced because of its deteriorating condition.  It is a vital link for the communities on both sides of the river.  About 11,000 vehicles travel over the bridge each day.  The existing bridge has narrow lanes with no shoulders, restrictive weight limits and requires a regular cycle of rehabilitation work.  The proposed new bridge would provide safer and more efficient travel for many motorists traveling between Franklin and Warren counties.

While MoDOT is excited to continue to improve Missouri’s transportation system, motorists are reminded that the existing Route 47 bridge is safe.
