Transurban has announced that Accelerate Maryland Partners (AM Partners) has decided not to proceed with the Maryland Express Lanes Project and as a result has today submitted a notice to terminate to the Maryland Department of Transportation (MDOT) in regard to the preferred developer agreement. Additional information below, per the Transurban press release:

AM Partners was originally selected in February 2021 as Maryland’s preferred developer for Phase 1 of the project. Since that time, extensive work has been undertaken on the project and draft concession agreement in partnership with MDOT. However, the project continues to face challenges including significant delays to environmental approvals, changing political landscape and environmental lawsuits that remain unresolved. Following extensive good faith negotiations by AM Partners, agreement with MDOT on the form of the concession agreement has not been reached and a committed section proposal will not be submitted by the deadline of 21 March 2023.
