SB 59 Maryland Senate · 2026 Regular Session

Transportation - Major Highway Capacity Expansion Projects and Impact Assessments (Transportation and Climate Alignment Act of 2026)

SB 59 requires Maryland’s Department of Transportation to conduct impact assessments for major highway expansion projects costing over $100 million, measuring their effects on greenhouse gas emissions and vehicle miles traveled. It mandates that projects include a multimodal transportation program (focusing on transit, bike paths, and pedestrian improvements) to offset emissions, with priority given to overburdened and underserved communities impacted by the project. The bill also requires the Department to evaluate all major capital projects in the Consolidated Transportation Program for climate impacts starting in 2028, aiming for net-zero or negative emissions from these projects. These requirements apply to projects not already funded or reviewed before 2026, aligning transportation planning with state climate goals.
