Details

Based on flood projections and flood history, elevate bridges to prevent inundation and reduce service disruptions.

Capital Cost

High

Operations & Maintenance

Low – assuming bridge is properly elevated to manage flows

Effectiveness

High – can reduce or eliminate flood risk

Flexibility

Low – it is generally cost-prohibitive to modify fixed infrastructure once constructed

Barriers to Implementation

Cost; permitting; potential downstream impacts

Equity

Ensure the availability of alternate public transportation routes so that capital improvements do not impede commuting for public-transportation dependent communities and equity focus areas
