' t I DUIN A LN i y ��: �� . : � r ., r. r _ r�r r t • Three widening alternatives were evaluated, each of which would provide a new street right -o£ -way of 120 feet throughout the project limits, except for the segment between Santiago Creek and Memory Lane, which would remain at its_ present ioMoot right -of -way configuration. The proposed right -of -way between Santiago Creek and Warner Avenue would provide three lanes. of through traffic in both directions, plus a 14 -foot _wide, raised center median that could be fully or partially landscaped, throughout the entire project corridor. The remaining segment between Santiago Creek and Memory Lane would be modified, without widening the street section, to provide three lanes of through traffic, in each direction, divided by a 14 -foot wide, raised center median, consistent with the street section along the rest of the corridor. Additional right -turn only lanes and left -turn lanes would also be added to several of the major intersections. Far -side bus turn -guts are proposed at the following_ intersections: Warner Avenue: northbound and southbound Edinger Avenue: northbound and southbound McFadden Avenue: northbound and southbound First Street: northbound and southbound Santa Ana Boulevard: eastbound At several intersections, the right -of -way will need to be expanded somewhat beyond the standard 120 feet to safely accommodate the additional right and left turn lanes and the far side bus turn-outs. Similarly, additional right -of -way will be needed along the east and west legs of several intersections to achieve completely improved geometries in accordance with County and City standards and to safely accommodate projected levels of traffic. 'l Ten east -west through streets are proposed to become cul -de -sacs to further decrease congestion along Bristol. Street (see Figure 20). The alternatives each envision widening the existing 53 -foot wide bridge across Santiago Creek to accommodate six through travel lanes. Please refer to Section IV.0 for a complete discussion of the proposed traffic and circulation system improvements. The alternative widening approaches evaluated consist of the three options described below. It should be noted that each of these alternatives would have the common features of maintaining the existing right -of -way and centerline north of Santiago Creep and would also have a common design between 17th Street and Santiago Creek. This common design feature would I1 -1
