On the west side of the Union Pacific tracks near Fresno’s Chinatown, the abutment walls are up for the bridge that will cross over the Tulare Street underpass along G Street. Crews are also working on three retaining walls and a pump station that will help with drainage of water that may accumulate along the underpass. When complete, the Tulare Street Underpass will be 22 feet below grade and will include pedestrian access.
