Longmont-to-Boulder: IBM Connector Trail

Longmont-to-Boulder: IBM Connector Trail

The IBM Connector Trail is a planned multi-use regional trail that will connect the Gunbarrel community to the Boulder Reservoir and the larger City of Boulder parks and trails system. The trail connection is approximately 0.6 miles long with a primary crusher fines surface. Three underpasses (two highway and one railroad) and two bridges will be constructed as part of the trail.


The trail is under construction and is expected to open to the public in June or July of 2017. Please do not use the trail until it is completely finished as it is unsafe in its current condition.

Funding & Alignment

The project will be paid for using Federal Transportation Enhancement funds and by Boulder County. Federal funds are part of the Longmont-to-Boulder Regional Trail Connections project for which Boulder County was approved for funding in 2007. Boulder County is using dedicated funds for trail implementation passed by county voters in 2001 and extended in 2007.

The preferred trail alignment was shaped by the IBM Trail Connector Community and Environmental Process (CEAP) Report that was completed by the City of Boulder in 2005. The CEAP was the result of public input and an environmental study. Boulder County is constructing the trail, but it will be owned and maintained by the City of Boulder.
