An auxiliary lane will also be <br /> constructed between the Bird Road on-ramp to eastbound SR 132 and the <br /> eastbound SR 132 direct off-ramp to southbound I-5. The weaving evaluations _ <br /> assume that these auxiliary lanes are in place and available for weaving(Omni- <br /> Means 2005). Table 3.L-10 presents the projected weaving operation between <br /> the I-5/SR 132 and SR 132/Bird Road interchanges. Location 1 is the weave on _ <br /> westbound SR 132 between the southbound I-5 direct off-ramp to westbound SR <br /> 132 and the westbound SR 132 off-ramp to Bird Road. Location 2 is the weave <br /> on eastbound SR 132 between the Bird Road on-ramp and the eastbound SR 132 <br /> direct off-ramp to southbound I-5. All weave sections are projected to operate at — <br /> LOS`B"or better during both the AM and PM peak hours. <br /> Table 3.L-10.
