• 1. Severe SR 1 AM & PM peak period – peak

direction congestion of long duration

• 2. Congestion and unreliability keeps METRO

from using SR 1 for bus services

• 3. SR-1 shoulders lack the width and

structural section to support bus-on- shoulder operations without significant construction – although there is some potential in the SB direction

• Interim Bus-on-Shoulder - Alternative 1 –

Segment C from RR bridges to Freedom Boulevard is the best near term opportunity

4.

Existing and planned auxiliary lanes will provide an opportunity for bus-on- shoulder operations, Alternatives 2A &

• 2B. Must be implemented in coordination

with each stage of the auxiliary lane project.

• Alternative 2A is the most effective with the

least cost. Operationally superior.
