Description

Presentation: The I-35E MnPASS Design Build is a $98 million reconstruction project that includes construction of nine bridges. Design and construction of the corridor, which begins at Maryland Avenue and extends north to Little Canada Road, is occurring now under a fast track schedule. The Ames Team Technical Proposal identified the Larpenteur Bridge as an excellent candidate for MnDOT to utilize Slide-In Bridge Construction for the first time on a Minnesota highway due to its high traffic volumes and importance as an east-west corridor crossing I-35E. A bridge slide is an Accelerated Bridge Construction (ABC) technique which allows for shorter closure durations on busy roadways. The process is as follows:

Temporary supports are constructed alongside the existing bridge.
The proposed bridge superstructure is constructed from the beams up including the deck and the barrier rail.
The existing bridge is demolished.
The proposed abutments and pier are constructed.
The bridge superstructure is slid from the temporary supports on to the new abutments and pier.
The approach panels are poured.
The bridge is opened to traffic.

There will be a test slide on the night of July 8^th with the full slide occurring on the night of Wednesday, July 9^th. Note: The bridge slide will not occur during this tour. The project team will give a short presentation on the design of the bridge at the site. The project team includes Ames Construction (Prime Contractor), Alliant Engineering (Lead Design Engineer), and Michael Baker International (Bridge Design). The owner is the Minnesota Department of Transportation. The oversight team is led by WSB. Space is limited to 30 participants so register early! Only the first 30 people who register online will be able to attend.

Presentation: The presentation will begin at 3:00pm. Please park on the west side of the I-35E Service Road as shown in the link: https://www.google.com/maps/@44.9927892,-93.0881233,18z?hl=en
