Page 4 of 5 Reference: Brian Drive, Culvert Bridge 02J04 Posting Analysis o Assumptions: According to the bridge inspection report, each culvert is 89 feet long. The structural plate liner would be applied to the 32Ó wide roadway section plus 8Ó on each side for a total length of 48Ó per culvert. o 2 Culverts x 48 LF x $2,700/LF = $260,000 for plate liner o Estimate $60,000 for hydraulic analysis and other indirect costs Option 4 Î Replace Culvert: $650,000 4 Funding If the City were to move forward with improvements to the culvert, there are two likely sources of funding: local (City) funds, or State Bridge Funds. Local funds: If the City wishes to pursue options 1 or 2, they would need to be funded entirely from local funds. State Bridge funds: The state legislature has regularly appropriated funds to bridge replacement and rehabilitation through general funds, bonding, or both. Option 4 (full replacement) would be eligible for state bridge funds. Option 3 can only be eligible for bridge funds if a post-rehabilitation load rating and inspection determines that the bridge meets load requirements. There is a fairly significant amount of risk with this approach, and thus, MnDOT has not previously approved bridge funds for a bridge lining project. There are currently no bridge funds available, but the legislature may appropriate new funds either in a 2025 special legislative session, or in the 2026 legislative session. As a city with a population of 5,000 or less, Centerville would be eligible for 100% of the engineering design and bridge replacement construction costs, less a $10,000 match for engineering and $10,000 match for construction. To be eligible for funding appropriation, engineered design and construction plans must be completed and approved by MnDOT. If funding is not available at that time, the project will be added to the waitlist. 67
