Daniel Boone Bridge Project

  • Client:Missouri Department of Transportation
  • Location:St. Louis, Missouri, USA
  • Contract Amount:$110,900,000
  • Project Size:2,615 feet
  • Contract Type:Design-Build
  • Markets Served:Civil
  • Architect/Engineer:Burns & McDonnell

Alberici, with joint venture partner Walsh Construction and design partner Burns & McDonnell, served as the design-build contractor for the new I-64 Daniel Boone Bridge project.
 
The project included design and construction of a new bridge on I-64 over the Missouri River between St. Louis and St. Charles Counties, replacing a deteriorating bridge built in 1935. It also included a shared-use path connecting the Katy Trail with the Monarch Levee Trail and the addition of a fourth travel lane.
 
The new bridge measures 2,615 feet with a main navigational span of 510 feet and two intermediate back spans of 370 feet. It is a parallel flange plate girder design with flexibility to add a fifth vehicular lane in the future. The Alberici team's design significantly reduces maintenance costs during the 100+ years of expected service life.
 
Notable construction quantities include 5,850 tons of weathering steel girders and 12,800 cubic yards of concrete with 1,920 tons of reinforcing steel. Cofferdams were built to allow for construction of three bents in the dry. The other seven bents were constructed on land or in a temporary causeway.
 
The Alberici team maintained all travel lanes during peak travel hours for the duration of the project with extremely limited shut-downs.
