​BALTIMORE, MD (August 28, 2020) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) and Federal Highway Administration (FHWA) today announced a 30-day extension of the public comment period for the Draft Environmental Impact Statement (DEIS) and Draft Section 4(f) Evaluation, which is being developed in compliance with the National Environmental Policy Act (NEPA) for the I-495 & I-270 Managed Lanes Study.

A 90-day comment period was originally provided on the DEIS, twice the minimum time required by FHWA. Based on input from community partners, stakeholders and local and federal officials, MDOT SHA supported extending the comment period to 120 days, and made a formal request to FHWA, which has authority to grant any extension. FHWA approved the request, and the public will now have until November 9, 2020, to submit comments on the DEIS. 

As part of the release of the DEIS on July 10, MDOT SHA, FHWA and its partner agencies also announced four virtual and two in-person public hearings, with an emphasis on public health, safety, and access as Maryland continues its COVID-19 recovery.

“Throughout the I-495 and I-270 Managed Lanes Study we’ve been committed to work in collaboration with community members and stakeholders,” Transportation Secretary Greg Slater said. “Extending the comment period to 120 days ensures the public has ample opportunity to review and provide feedback on the DEIS. The extension also supports our number one priority during the COVID-19 emergency: the health and safety of the public and our team.”

The I-495 & I-270 Managed Lanes Study considers ways to relieve congestion and improve trip reliability, mobility and connectivity for modes of travel, including transit, in the National Capital Region. The DEIS includes traffic, environmental, engineering and financial analyses of a No Build Alternative and six Build Alternatives involving high-occupancy toll (HOT) lanes or express toll lanes (ETL), sometimes in combination with existing high-occupancy vehicle (HOV) lanes on I-270.

MDOT SHA, FHWA and the Maryland Department of the Environment (MDE) has conducted three virtual public hearings and will conduct one more virtual and two in-person joint public hearings to provide opportunities for public comment on both the DEIS and the Joint Federal/State Application (JPA) for the Alteration of Any Floodplain, Waterway, Tidal or Nontidal Wetland in Maryland.

The DEIS review is the first of multiple environmental studies planned as part of the larger I-495 & I-270 Public-Private Partnership (P3) Program. The study has involved extensive outreach including four scoping open houses in April 2018; four public workshops presenting the Preliminary Range of Alternatives and Screening in July 2018; eight public workshops in spring 2019 on the Alternatives Retained for Detailed Study; and more than 180 meetings and events with communities, property owners, stakeholders and elected officials.
