Minnesota DOT Uses SPMT Technology to Speed Replacement of I-35 Maryland Avenue Bridge
Date Posted:	9/6/2012
Description:	The Minnesota Department of Transportation (MnDOT) recently used a Self-Propelled Modular Transporter (SPMT) for the first time to move the Interstate 35E Maryland Avenue Bridge in St. Paul. The bridge was moved into position in two sections and was part of a pilot demonstration of the SPMT technology for MnDOT. The SPMT technology will enable MnDOT to close the bridge for approximately 60 days as compared to four months using traditional construction methods. The bridge is expected to be open to traffic in mid-September after some additional work is done around the bridge. This project was partially funded through an FHWA Highways for LIFE demonstration project grant.
