part of the project involves the reconfiguring of the pentagon interchange to provide greater access to army navy drive, as well as the closing of the on-ramp—from the southbound hov lanes to the mainline interstate southbound—located just west of the pentagon interchange. all existing hov interchanges within the project's scope will also become tolled, except for the northbound exit and southbound entrance at seminary road, which will remain toll-free while retaining its hov-only restriction.
