I-35E Cayuga Bridge Replacement
Project Type: Bridge Replacement
Client: Miknnesota Department of Transportation (MnDOT)
In the Spring of 2012, LHB was hired to assist the MnDOT Office of Bridges and Structures with design services related to replacement of the bridges on and adjacent to Interstate I-35E near the Cayuga Street exit. While there were several bridge replacements involved in the overall $116 million project, LHB was responsible for the two (northbound and southbound) I-35E mainline bridges crossing Minnehaha Avenue and the BNSF railroad tracks just north of Phalen Boulevard.
The two bridges are nearly identical to each other and share a common pier. Each is a two-span, prestressed concrete girder bridge, 250-feet in length and over 86-feet wide to provide for five lanes of traffic each. The bridges featured aesthetic treatments on the substructures and were built under staged construction to accommodate at least two lanes of I-35 through traffic in each direction at all times during construction. The bridges were complete and opened for traffic in 2016.
