North Metro Rail ExtensionFollowing is one of five key study areas within the Northwest Area Mobility Study. Each of the five areas will be evaluated in context to produce a comprehensive set of solutions to improve overall mobility for the entire northwest area.
Northwest Rail Line, the study will evaluate the feasibility of providing commuter rail service to Longmont by extending the North Metro Rail Line from the currently planned end-of-line at 162nd Avenue and SH 7 in northern Adams County.
The study is developing and analyzing a variety of alignment options to extend the North Metro Rail Line to Longmont. Among them are:
- North I-25 EIS Alignment - This generally follows the Burlington Northern Santa Fe rail line northwest to CR 7 where it heads north to SH 119.
- Boulder Branch Alignment Option 1 - This generally follows the Boulder Branch Rail Alignment that RTD owns to US 287 where it heads north to Longmont.
- Boulder Branch Alignment Option 2 - This generally follows the Boulder Branch Rail Alignment that RTD owns to the abandoned Lafayette line where it heads north and west to Longmont.
- CDOT InterConnectivity Study I-25 Alignment - This generally follows I-25 north to SH 119.
Other potential routes will be determined by stakeholders and RTD through the study process.
The study will evaluate ridership estimates on potential alignments, refined cost estimates of an extension (including operating and maintenance costs) and potential impacts of this option on the location of the Longmont Station. If the North Metro Rail Line extension to Longmont is feasible, the study must help stakeholders and RTD determine whether Northwest Rail or the North Metro Line is the better way to provide commuter rail service to Longmont.
