According to the current FasTracks plan, RTD’s North Metro Rail Line will end at 162nd Avenue and SH 7 in northern Adams County. The Northwest Rail Line would follow US 36 to Boulder and Highway 119 to Longmont. The Northwest Rail Line’s original completion date of 2016 has been pushed back to 2044 because of estimated cost increases.
Bowing to political pressure, RTD agreed to fund another study to explore other alignment options. The Northwest Area Mobility Study, which kicked off in May 2013, will “evaluate extending the North Metro Rail Line … to Longmont. The study will help RTD to whether Northwest Rail or the North Metro Line is the better way to provide commuter rail service to Longmont.”
The study is developing and analyzing a variety of alignment options to extend the North Metro Rail Line to Longmont, including:
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.
