What is Safe and Sound?

MoDOT's Safe and Sound Bridge Improvement Program will repair or replace 802 of Missouri's worst bridges by October 31, 2014.


When will work begin?

The Safe and Sound program will improve 248 bridges in Missouri using a modified design-bid-build process, packaging the work by type, size and location of the bridge to accelerate construction schedules. Rehabiliation of 100 of these bridges began in spring 2009.

MoDOT solicited design-build proposals to replace the other 554 bridges in a single contract. This contact was awarded to KTU Constructors on May 21, 2009.

In the St. Louis region, there are 23 bridges listed in the Safe and Sound program. Five are in Franklin County, twelve in Jefferson County, five in St. Louis County and one in St. Charles County.


How much will the bridge replacement program cost?

The capital cost of construction for the design-build project is estimated to be $350 million to $500 million, while the modifieddesign-bid-build portion is expected to cost $150 million to $200 million. MoDOT will sell bonds to pay for the project, with annual payments of approximately $50 million. MoDOT will use roughly one-third of the federal bridge funds it receives each year to make those payments. The Safe and Sound bridge improvement program requires no additional funding.


Which bridges in my community will be impacted by the construction work?

At its November 2008 meeting, the Missouri Highways and Transportation Commission awarded approximately $1.47 million to the lowest bidder.  Starting in spring 2009, work began on five bridges in Jefferson County.


Safe and Sound signs have been posted on all St. Louis area bridges designated for rehab or replacement.


A complete list of all the bridges in the Safe and Sound Bridge Improvement Program and other information can be found on the MoDOT Web site at http://www.modot.mo.gov/safeandsound.
