Current Issues
This route suffers from poor scheduling at ? Station, here buses are timed to depart 3 minutes before W Line trains arrive.
Future Plans
The System Optimization Plan proposes to restore express route LX2 from Longmont to Denver via I-25 while eliminating Route LD1. All routes are proposed to serve the proposed SH 66 and Main St. Park-n-Ride lot. No changes to frequency or span of service are proposed.
