In a two-day operation last month, ironworkers placed the final steel for the new Stan Musial Veterans Memorial Bridge over the Mississippi River between St. Louis and St. Clair County, Ill. The final piece was an 80-ft long, 15-ton floor beam, shown above. The roadway is now complete and workers are preparing to build traffic barriers, pour the deck and do final stay cable tuning. The project is on track to be complete by early 2014. Photo: Missouri Department of Transportation
The new Stan Musial Veterans Memorial Bridge over the Mississippi River between St. Louis and St. Clair County, Ill., will relieve traffic on nearby bridges and allow drivers to experience less congestion, fewer crashes and fuel savings. The bridge measures 2,770 ft with span lengths of 635 ft, 1,500 ft and 635 ft. It also supports a roadway width of 81 ft and provides a 1,360-ft-wide navigation channel below. Two pylons rise 321 ft above the roadway and support 7,629 tons of A709-HPS 70W and HPS 50W deck-level steel. There are 68 stay cables per pylon, which connect to pylon cable anchor boxes (A709-HPS 50W) that weigh 932 tons. Fabrication of the bridge was performed by W&W/AFCO Steel (an AISC/NSBA member and AISC certified fabricator).
