ramp and the loop off ramp to eastbound SR-132. As shown in Table 31, all weave sections are ` projected to operate at Levels of Service "C" or better during both the AM and PM peak hour periods with the exception of LOS"D"projected during the PM peak hour at Location 2.

Under all three design alternatives, SR-132 was considered to be a four-lane freeway at the merge and diverge. As shown in Table 32, the on ramp merge from Bird Road to westbound SR-132 is projected to operate at LOS "F"during the AM peak design hour for all three design alternatives. As also shown in the table, the off ramp diverge from eastbound SR-132 to Bird Road is projected to operate at LOS"F"during the PM peak design hour for all three design alternatives. r TABLE 32 SR-132/BIRD ROAD INTERCHANGE RAMP JUNCTION OPERATIONS YEAR 2027 BASE CONDITIONS LEVELS OF SERVICE(LOS)WITH 4-LANE FREEWAY (ALTERNATIVES 1 THROUGH 3) SR 132/ Alternative 1 Alternative 2 Alternative 3 Bird AM Peak Hour PM Peak Hour AM Peak Hour PM Peak Hour AM Peak our PM Peak Hour Road Density Density Density Density Density Density Ramps j e/mi/lo LOS (PC/mi/In) LOS (PC/mi/In) LOS ( chniAn) LOS chni/1n LOS ( c/mi/In) LOS WB on from 34.9 F 4.8 A 34.8 F 4.8 A 34.8 F Bird Rd EB off to 71 A 40.9 F 7.0 A 40.8 F 7.0 A 40.8 F Bird Rd r Roadway Segment Operations: With the Bird Road interchange project, SR-132 is proposed to be a four-lane freeway through the Bird Road interchange and immediately to the east and west of the interchange for all three design alternatives. Table 33 presents the projected peak hour levels of service on these SR-132 study segments. As shown in the table, the westbound SR-132 segments to the east, to the west, and within the Bird Road interchange are projected to operate at LOS "E/F" during the AM peak r, hour. As also shown in the table, the eastbound SR-132 segments both to the east, to the west and within the Bird Road interchange are projected to operate at LOS "E" during the PM peak hour. Table 33 also shows that LOS "E" is projected on westbound SR-132 during the AM peak hour, and LOS "E" is _ projected on eastbound SR-132 from the I-5/SR-132 interchange east to the end of the four-lane freeway segment while the two-lane highway segment on SR-132 further east of the I-5/SR-132 interchange is projected to operate at LOS "F" during both peak hours. Finally, all three non state highway facilities including Bird Road,Koster Road and Blewett Road are projected to operate at LOS "C"or better during both peak hour periods. 2nd Draft DeSilva Gates Quarry Trafc&Circulation Analysis 37 October 2005 Jones&Stokes (R90577S002/25-4000-02) in.
