Constrained vs. Corridor Typical Constrained
Why are Construction Costs Higher in Constrained?!? • Additional Pavement & Aggregate needs • 14’ inside median vs. 4’ shoulder • Loonheads – U-turns for truck/agg equipment • Crown correction–cheaper than drainage structures • Still need R/W (south side utility poles)
R/W cost and Constrained Viability • Current R/W Costs - $12K/acre • Provided by District Real Estate Rep • When Construction + R/W becomes equal between alternatives • $46K/acre – Assumes HTCB in both alternatives • $66K/acre – HTCB only in constrained
Pros and ConsComparison of Alternatives • Corridor Typical • Pros • Lower Construction Cost • Introduction of alternative intersection treatment types – RCUTs • Lower Maintenance Cost • Cons • Additional farmland/wetland impacts • Constrained • Pros • Less impacts to farmland/wetlands • Evaluation for other corridors statewide • Cons • Higher Construction Cost • Higher Maintenance Cost
Nicollet Bypass Discussion • Construction • $10M - $15M • 4-lanes only • No Interchange • R/W • $4M • 4-lanes • Relocations • Interchange *Currently Unfunded
