Exhibit 6-17 DEFICIENCIES BY SEGMENT (Continued) From MP To MP SR 77 Segment Deficiencies 69.8 69.5 Fort Lowell Road to Miracle Mile Roadway: Poor future LOS due to heavy congestion. High driveway density on east side. Access analysis indicates need for driveway consolidation. Pedestrian: Discontinuous sidewalks. Crosswalk on west side of Oracle Road at Miracle Mile intersection is not ADA compliant. 69.5 69.0 Oracle Road to Fairview Avenue Roadway: Non-standard median lighting. High driveway density. Access analysis indicates need for driveway consolidation. Pedestrian: 69.0 68.5 Fairview Avenue to Flowing Wells Road 68.5 68.1 Flowing Wells Road to Interstate Discontinuous sidewalks. Roadway: Non-standard median lighting. Highway driveway density. High crash rate intersection at Flowing Wells Road intersection (ranked No. 2). 123 percent increase in crash rate at Flowing Wells Road intersection. Access analysis indicates need for driveway consolidation. Transit: Transit buses cannot make southbound to eastbound right-turn at Fairview Avenue without encroaching into opposing traffic lanes because of position of utility poles at the corner. Pedestrian: Discontinuous sidewalks. Roadway: Poor future LOS due to heavy congestion. Eastbound left-turn lane at Flowing Wells/Miracle Mile intersection experiences high volumes during peak hours. Non-standard median lighting. High driveway density. Pedestrian: Discontinuous sidewalks. Bicycle: No bicycle facilities. Existing congestion level is year 2002 from PAG. Future congestion level is year 2030 with PAG 2030 RTP and RTA projects assumed in place. SR 77/Oracle Road Multimodal Corridor Profile Study May 2007 Final Report Page 6-30
7. INVESTMENT OPTIONS 7.1 SUMMARY OF INVESTMENT OPTIONS TO ADDRESS CAPACITY DEFICIENCIES The roadway deficiencies described in Chapter 6 of this document were examined on a segmentby-segment basis and roadway improvement options were developed to address these deficiencies. These improvement options were then compared along the entire corridor to provide coordinated and comprehensive alternatives for consideration. Further analysis was then conducted through traffic simulation modeling to refine feasible capacity alternatives and determine the effects of the grade-separated interchange (GSI) alternatives as compared to an eight-lane widening alternative. An analysis of the potential right-of-way impacts of widening portions of the corridor to eight traffic lanes was also conducted to evaluate the potential rightof-way cost of this option and impacts to adjacent properties. A summary of the capacity improvement alternatives developed for consideration is provided below. It must be noted that the major improvements described would not necessarily be implemented together, but rather these concepts are presented as alternative ways of maintaining or improving traffic operations and safety along SR 77. It should also be noted that it is assumed that these improvements are in addition to those improvements that are already planned or programmed and are included in the PAG Regional Transportation Plan at the time this study was conducted. 7.1.1 Development of an Alternative High-Capacity Corridor One option is to develop a parallel high-capacity controlled access corridor to divert traffic from SR 77. The concept is to provide sufficient capacity and travel speed on a parallel route such that enough traffic would be diverted away from SR 77 to reduce the need for other major capacity improvements (e.g., widening to eight lanes or constructing grade-separated intersections). This could be accomplished through the use of series of GSIs along a parallel route (e.g., La Cholla Boulevard) or through the development of a fully access controlled freeway corridor to the west of SR 77. The alternative corridor concept is illustrated in Exhibit 7-1. The corridor could extend as far north as the SR 77/SR 79 junction, thus providing an alternative route for traffic to and from the anticipated development north of the Pima County/Pinal County line. It would connect to Tangerine Road, already planned as a high-capacity corridor connecting to I-10 on the west. This new corridor would extend south, potentially connecting to one or more high-capacity corridors extending east across the core of the urban area. An analysis of this alternative corridor concept was conducted in The Oracle Road Corridor Study (June 20, 2003) prepared for the Town of Oro Valley, which included an analysis of the impacts of a series of grade-separated intersections (GSIs) along La Cholla Boulevard from Tangerine Road south to River Road on SR 77 traffic through the Town. This analysis included the widening of La Cholla Boulevard to a six-lane divided facility. The results indicate that these improvements along La Cholla Boulevard have little impact on the traffic volumes on SR 77. This is consistent with the PAG regional traffic model forecasts that include significant widening improvements along both La Cholla Boulevard and La Cañada Drive, which appear to SR 77/Oracle Road Multimodal Corridor Profile Study May 2007 Final Report Page 7-1
