ST. LOUIS - The Missouri Department of Transportation and Massman Traylor Alberici, the joint venture constructing the new I-70 bridge over the Mississippi River plan to install the final steel in the bridge later this week.
Crews will close the gap between the Illinois and Missouri sides of the bridge on July 25 and July 26, weather permitting. Three pieces of steel will be separately installed as part of the process to close the gap.
On July 25, starting at 8 a.m., crews will be installing the two edge girders for the bridge. These 10-foot long, six-foot high steel girders go on the upstream and downstream sides of the bridge, connecting to those girders which have already been put in. Because of adjustments and necessary iron work, that work is expected to take much of July 25.
On July 26, at 9 a.m., crews will be installing the final piece of steel - the 30,000 pound floor beam which goes between the two edge girders. This final piece is expected to take around two hours to set into place and install.
Members of the public interested in viewing the work can safely view construction from the pumphouse alongside the river near the Mullanphy entrance to the river wall. A map to the pumphouse is here: http://www.newriverbridge.org/documents/viewingplatform.pdf. Parking is limited and people wanting to view construction will need to make sure roadways and the Riverfront Trail remain open to traffic.
