Demolition, site work, paving and new construction of a bridge / tunnel in Orono, Minnesota. Conceptual plans call for the demolition of a bridge / tunnel; for the construction of a bridge / tunnel; and for site work for a bridge / tunnel.

Replace Bridge #90623 along Brown Road (CSAH 146) over the Luce Line State Trail in the City of Orono. Purpose & Description: The existing bridge (built in 1955) consists of a timber structure with a concrete deck that extends over Long Lake Creek and the Luce Line State Trail. The timber material throughout the structure has experienced advanced deterioration. In addition, the concrete deck is showing signs of extensive wear due to the frequency and size of visible cracking. A full replacement is being recommended as routine maintenance and repair activities are no longer cost effective in preserving this bridge asset. As a result of a routine bridge inspection, weight restrictions prohibiting certain types of commercial vehicles were introduced in 2014. The proposed project will implement a new bridge that is designed for a 75-year service life. The completion of this project will ensure that a grade separated crossing of the Luce Line State Trail is retained to eliminate conflicts for people walking and biking along the trail underneath the bridge. Additionally, the existing railing and guardrail will be upgraded to satisfy current design standards to ensure user safety. Furthermore, this project will eliminate weight restrictions along a collector route through the Orono Area.
