I don't think there's any recent news about that, I suspect such a bridge would still be opposed by the local community.
a collection of Montgomery County, Maryland NIMBYS, civic activist obstructionists, environmentalist obstructionists, anti-highway/pro congestion obstructionists and promoters of the Montgomery County Agricultural Reserve.
FTFY.
There is conventional wisdom that everyone in Montgomery County is opposed to such a project and that everyone is in favor of public transit - and say that the County Council has made transit "a priority." Most residents of Montgomery County do not make transit a priority and do not use public transit to get to and from work (according to Census Bureau ACS) - and they never have.
The groups and persons mentioned above loudly proclaim opposition to new river crossings whenever they get a chance, but it has never been before the voters of Montgomery County. Everyone was supposed to have been in favor of not building MD-200 (ICC) and removing it from planning maps, but that was built anyway over those same always loud and always angry groups raising objections - at the end when an ICC FEIS was approved, all of their objections had been addressed in a very long document, but they filed a federal lawsuit anyway, which was dismissed after about a year.
EDIT: It is also important to note that there once plans for an Outer Beltway crossing of the Potomac River between the I-495 American Legion Bridge and White's Ferry - the location shifted around several times, and most recently was proposed for Blockhouse Point (
location). That was cancelled in the 1970's when hysteria over "growth" was at its peak in Montgomery County under the leadership of the late Idamae Garrott, a longtime Montgomery County politician, who never met a highway project she did not wish to cancel (she was also anti-all-new-development). The current Montgomery County Executive, Marc Elrich, is a direct political heir to Idamae Garrott.
