Concerns over traffic flow and intersection design took center stage at the Los Alamos County Transportation Board meeting on August 7, 2025. A key discussion highlighted the need for improvements at the Trinity Diamond intersection, where two car streams converge, creating potential bottlenecks.

One board member pointed out that while Diamond Drive generally has more capacity than necessary, Trinity Diamond stands out as an exception. They argued that the current design is not optimized, particularly criticizing the right-hand slip lane coming from Omega Bridge. "Every time I take the car, I'm in traffic behind people going the right lane slip lane," they noted, suggesting that the lane often leads to congestion rather than efficiency.

The member proposed a redesign that could maintain the same traffic throughput while incorporating a dedicated bicycle lane. They emphasized that the existing bicycle lane is positioned in a stressful area for cyclists, sandwiched between vehicles. This redesign could enhance safety for both cyclists and drivers.

Additionally, the discussion touched on the challenges of snow removal in relation to new designs. The board member raised concerns about how snow plows would navigate painted lines and barriers, suggesting that specialized equipment might be necessary to ensure efficient snow clearance.

The meeting underscored the importance of re-evaluating intersection designs to improve traffic flow and safety for all road users in Los Alamos County. As discussions continue, the board will need to consider these insights to enhance the community's transportation infrastructure.
