As the Regional Transportation District (RTD) seeks community input on the proposed Diagonal Flyer service between Boulder and Longmont, commuters and residents are getting a chance to shape the future of transit along the CO 119 corridor. The upgrade from the current Route BOLT to a Bus Rapid Transit (BRT) system promises a more efficient travel experience. With a survey open until June 30, RTD is collecting data on passenger habits and preferences to inform the service's development, as reported by Boulder County.

Bus Rapid Transit is known for marrying the capacity of rail with the cost efficiency of bus transport. The anticipated Diagonal Flyer BRT service aims to connect Boulder and Longmont with speed and reliability. The new route is expected to bring about a transportation renaissance, providing residents with enhanced options that could significantly reduce traffic congestion. With Boulder County as one of its partners, the RTD is making sure that local needs are being served by integrating state-of-the-art technologies to appeal to future users, according to Boulder County.

The CO 119 BRT project encompasses several infrastructure improvements to facilitate a seamless transit system. Key elements include new Bus Rapid Transit and queue bypass lanes, upgraded transit stops, and a Park-n-Ride facility to cater to north Longmont's growing demand. As part of this comprehensive plan, the initiative also includes the 119 Bikeway project, enhancing the alternative travel options for cyclists in the area. According to Boulder County, these improvements are geared toward establishing a transit service that is not just faster and safer, but one that harmoniously integrates with various modes of transport.
