Notice of upcoming RTD public meeting

Starting January 13, 2019, RTD is proposing to discontinue service on routes LD1 and LD2 south of US 36 due to low ridership and duplicate service on FF routes. Service would also be rerouted south of Lafayette Park-n-Ride via US 287, west Dillon Road, SH42 (96th Street), Interlocken Parkway, Vara and into US 36 & Flatiron Station. Service frequency would be increased to 60 minutes all day between 5:30 a.m. and 10:30 p.m., combined with LD1 and LD3 rush-hour frequency, 30-minute frequency would be created between both routes between 8th & Coffman Park-n-Ride and US 287 and Dillon Road. Route 225 would be renamed between Lafayette Park-n-Ride and US 36 & Broomfield Station to Route LD3 and reduce service frequency between US 36 & Broomfield Station and Lafayette Park-n-Ride to 60 minutes, maintaining the current service span. Route 225 would be retained between Downtown Boulder Station and Mohawk and Talbot. Additionally, Route 225 service would move from East Boulder Recreation Center to Mohawk and Talbot and weekday rush-hour service frequency would increase to 15 minutes in both directions. Contact RTD for more information about these proposed changes. 

The official Longmont stance is for RTD to wait on any service cuts involving Longmont until more evaluation is completed on the full effects of these cuts on our transit users.

The date/time/location of the meeting is:

Wednesday, September 26, 2018

The Regional Transportation District (RTD) is the public transportation service provider for the Denver Metro region, and it includes bus service to/from Longmont. RTD services are funded through a combination of federal transportation dollars, fares and a .6 percent sales tax (6 cents for every $10 dollar purchase). Because one size does not fit all, RTD attempts to provide appropriate service for different situations and clientele. Service types include:

  • Bus Service: Local, Express, and Regional
  • Light Rail Service (does not currently extend to Longmont)
  • Call-n-Ride
  • Park-n-Ride
  • SkyRide (service to Denver International Airport from designated Park-n-Ride lots throughout the region)
  • Access-a-Ride paratransit program
  • Transportation to special events such as Broncos and Rockies games can be accessed at designated Park-n-Ride lots for a cash-only fare

Eco Passes, which can be purchased by employers for their employees, provide unlimited access to all transit services with the exception of the Broncos and Rockies Rides.

The FasTracks plan includes rapid transit (commuter- or light-rail) in six corridors throughout the Denver Region. One of the corridors includes US-36 from Denver to Boulder and the Diagonal Highway (SH-119) from Boulder to Longmont. FasTracks includes a commuter-rail connection from Denver through Boulder to Longmont via the existing Burlington Northern/Santa Fe Railroad line.

The Northwest Area Mobility Study (NAMS) developed a prioritized list of mobility improvements for the northwest area of the Regional Transportation District’s (RTD) service area. The goal was to determine if there is a more cost-effective way to improve mobility in the area that could be implemented sooner than current projections for when RTD could complete the Northwest Rail Line to Longmont. The study began in the spring of 2013 and was completed in 2014. Visit RTD FasTracks to view the Northwest Area Mobility Study.
