On Route 84, operations are acceptable except for queuing at Pigeon Pass and I-680 westbound in the morning peak period (1-mile queue at each location) and at Pigeon Pass and I-580 eastbound in the evening peak period (2- mile and 0.5-mile queues, respectively). The following are important linkages between projects: • The west auxiliary lanes from First Street to Isabel would facilitate access to SR 84. • I-680 ramp metering should precede the HOV projects or be built with them to give HOVs priority and to improve operations when there is an incident. • The SB I-680 HOV lane should precede the I-680/1-580 system interchange improvements to give additional capacity on I-680. • The EB I-580 climbing lane should precede an EB mixed-flow lane to give sufficient capacity on the Altamont Grade.
