Operational Baseline and Structural Health Monitoring for the 2nd Avenue Network Arch Bridge

A skewed, unbraced network arch bridge is being constructed to carry the 2nd Avenue over I-94. This 245 ft long, 96 ft wide structure will carry vehicular traffic, bicycles and pedestrians in separate dedicated lanes. The unique structural configuration and the use of innovative accelerated bridge construction (ABC) techniques make this one of the most significant projects in the United States. The bridge skeleton, consisting of trapezoidal steel arch ribs, tie girders, end diaphragms, and steel floor beams will be assembled in a staging area near the bridge site. This bridge skeleton will be moved into place using self-propelled modular transporters (SPMTs) during a weekend closure of I-94. Following SPMT move and placement of the skeleton on permanent bearings, the rest of the construction activities will be completed. The stresses in several major structural elements are monitored using a structural health monitoring (SHM) system to capture the stresses during construction and in service.
