Construction is moving forward on the new pedestrian/bike bridge over the Cannon River just below the Byllesby Dam.
The north and south bridge abutments and the north pier have been poured but the high water flows have prevented any construction on the south pier, according to Kim Waldof, Principal Engineer, Minnesota department of Natural Resources.
"We are in the process of finalizing the review and approval of the truss bridge fabrication drawings," said Waldof. "We will know more on the construction schedule in late-September/early-October once we know when the truss bridge will be fully fabricated."
The bridge, which will connect from Dakota County parkland on the north to Goodhue County parkland on the south, will be about 300 feet long. It will have a width that will be 12 feet clear between railings. The deck will be approximately 45 to 50 feet above the Cannon River.
The bridge was bid at about $1.5 million. Federal funds cover about $1,075,000 of the project and State Funds another $425,000.
The structure will use approximately 380 cubic yards of concrete and 57,000 pounds of steel reinforcement bars.
Plans call for eventually linking the bridge with a new trail near the river on the Goodhue County (south) side that would link up with the Cannon Valley Trail near Hannah's Bend Park and the DNR Gemini Aquatic Management land north of the Fairgrounds donated by the Weinel family.
