The Maryland Department of Transportation (MDOT) State Highway Administration (MDOT SHA) in the USA has formally recommended Alternative 9, adding two high-occupancy tolls (HOT) lanes across the American Legion Bridge to I-270, and north on I-270 to I-370. This alternative also would add a bicycle and pedestrian connection across the new American Legion Bridge.

Buses and vehicles with three or more people would be able to travel the new HOT lanes free of charge, reducing dependence on single-occupant vehicles and providing opportunities for faster, more-reliable bus transit service, carpooling, and vanpooling throughout the region. Under this MDOT Recommended Preferred Alternative (MDOT RPA), existing travel lanes throughout the corridor will be retained and will remain free for use by all motorists. Drivers of single-occupancy vehicles only would pay if they choose to use the managed lanes. 

The result would be significant operational and multimodal network benefits while retaining existing travel lanes as free lanes. MDOT SHA will not seek permits/authorizations outside of Phase 1 South: American Legion Bridge I-270 to I-370 until additional design details are developed in coordination with applicable agencies and environmental review is completed.
