House adopts amendment on major‑highway bill exempting Bay Bridge while directing greenhouse‑gas assessments for mega projects
Summary
An amendment to the Transportation and Climate Alignment Act exempted reconstruction of the William Preston Lane Jr. (Chesapeake Bay) Bridge from greenhouse‑gas assessment requirements; sponsors said MDOT will assess net project emissions for multi‑hundred‑million‑dollar expansion projects and may alter projects or program offsets.
The House on Feb. 25 adopted an amendment to a bill that requires greenhouse‑gas assessments for large highway expansion projects. Amendment number one carved out an exemption for construction or reconstruction of the William Preston Lane Jr. Memorial (Chesapeake Bay) Bridge and related US‑50 work from the bill’s scope.
Sponsors described the bill as focused on the largest highway expansions (five to six projects in the near term) and said the Maryland Department of Transportation (MDOT) would evaluate whether a project causes a net increase in greenhouse‑gas emissions. "For those projects, MDOT will do an assessment on whether or not the project itself will result in a net increase in greenhouse gas emissions," a sponsor said, adding the department may modify a project or program separate mitigation projects to reach net neutrality while still meeting travel‑demand needs.
A delegate from Anne Arundel County pressed the sponsor on practical implications: whether assessment findings would affect financing and whether embedded material emissions (for example, emissions from cement and concrete) would be counted. The sponsor replied that MDOT should consider the project in totality — vehicle miles traveled and construction material lifecycle — and that options include project modification or programming other projects to offset net emissions.
The amendment was adopted and the favorable report, as amended, was adopted by voice vote; House Bill 437 was ordered printed for third reading.
