What metro Denver needs, is a metro-wide sales tax, boarding tax and gas tax initiative. Perhaps 0.3% sales tax, 3% boarding/lodging tax and a 6 cents/gallon fuel tax increase for transportation projects. Make it a 30-year tax to raise ~$30 billion in funds, but to all be spent in the first 15 years of that duration, via bonding.
Allocate $15 billion to road and highway projects, with an emphasis on adding grade separated intersections to high capacity roadways, expressways and freeways. Adding AI traffic management technology and managed lanes to highways and expressways. Adding AI traffic signal managing technology to all major arterial roadways.
$10 billion allocated for the following transit improvements:
Add true BRT infrastructure to all major transit routes
Add extra tracking to existing rail lines to create express service passing track.
Complete NW corridor rail as a fully electrified and 150 mph high speed corridor.
Eleminate 50% of existing grade crossing on current rail network.
Add some small rail extensions and spurs to the network
Then the final $5 billion would be allocated to build a subway link from Broadway/I-25 Station to Civic Center Station to Union Station. This should use LRT technology for full integration with all the LRT lines converging on Broadway Station. This also will provide a third route for accessing downtown, relieving the Central Corridor and CPV corridor. Civic Center should have a large underground station built not only to accommodate this, but to also allow for built-in east/west expansion capacity.
Then also terminate full size LRT vehicle central corridor lines at Convention Center Station and fully convert the downtown loop into a high frequency streetcar starter system. Or possible take the LRT's underground coming out of the convention center and tie it into the subway line into Union Station. Either option converts the downtown loop into a single or double car streetcar line.
