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.
