Future Iliff-Jewell light rail corridor

Longer-term transit service (post 2030) could potentially include rapid transit. The median within E-470 has been identified for a future rapid transit facility, exact nature unknown at this time. Jewell Avenue has also been identified for possible rapid transit service extending into the NEATS area from the west.

Note:  The light rail line extends west from the E-470 interchange.  The only explanation I see is that it will extend all the way to Iliff/I-225.  Since there is no room on Iliff for light-rail, I think it will be elevated.
