Abstract:In the mid-2000s, over 10% of Missouri’s bridges were rated serious (Condition 3) or poor (Condition 4) under the Federal Highway Administration (FHWA) National Bridge Inspection Standards. The timeframe to repair the approximately 1,100 bridges using MoDOT’s standard capital programming approach was too long. Missouri accelerated the rehabilitation or replacement of 802 of these bridges under the Missouri Safe & Sound Bridge Improvement Program. MoDOT pursued a Public–Private Partnership to construct and maintain the bridges for 20 years. That procurement was found unaffordable during a major recession in 2008. Subsequently, the program was delivered by more traditional financing and project delivery. The program was completed with GARVEEbond financing and a combination of D-B and D-B-B procurement. Five hundred fifty-four of the bridges, known to be replacements, were bundled into a single D-B project. The remaining 248 bridges, primarily major rehabilitations, were delivered by conventional D-B-B. Those bridges were bundled into bid packages of 2 to 10 bridges each.
