6.4.1 Open House Comments on Pedestrian Improvements A sample of public comments received at the first round of open houses related to pedestrian improvements includes: • The combination of shared bicycle/skate/pedestrian paths are good because they allow people to travel away from traffic. • Look into better medians for pedestrians. • Trying to cross Oracle Road (at Orange Grove Road) is too dangerous. Cars turning right from Orange Grove Road do not pay attention to pedestrians. 6.5 BRIDGES AND DRAINAGE STRUCTURES Bridge condition data were obtained from ADOT’s bridge record, which is maintained by the ADOT Bridge Group. Reported sufficiency ratings (SR) were used to determine a bridge’s condition. The bridge sufficiency rating is expressed as a percentage in which 100 percent would represent an entirely sufficient bridge and zero percent would represent an entirely insufficient bridge. Bridges with sufficiency ratings at or below 80 percent are classified as structurally deficient structures and are eligible for rehabilitation. Bridges with sufficiency ratings below 50 percent may need replacement. Exhibit 6-13 provides a list of the structurally deficient structures on SR 77. None of the bridges have sufficiency ratings less than 50 percent, so none are identified as being eligible for replacement based on the sufficiency rating.

arriers are geometrically deficient, they are structurally adequate. The Bridge Management Section did not recommend any revision to these existing bridge barriers. In addition to structurally deficient structures, there are functionally obsolete structures. Functionally obsolete structures include bridges with horizontal and vertical clearances or other functional limitations which met AASHTO clearance standards when originally constructed, but which may not meet updated standards. None of the structures on SR 77 were identified as functionally obsolete in the bridge record. Based on input from the Central Arizona Association of Governments a box culvert at Oracle Junction (approximately MP 91) is recommended to be extended in order to move the existing culvert headwalls out of the clear zone. 6.6 PAVEMENT The Pavement Serviceability Rating (PSR) of each segment of SR 77 was identified from the current Highway Performance Monitoring System data on SR 77 as part of the project inventory. Most of the segments on SR 77 have a PSR rating over 3.0, representing pavements that exhibit few, if any, visible signs of surface deterioration. The segments between MP 69.80 and MP 71.30 have PSR ratings slightly under 3.0; however, these segments were part of a recently completed pavement overlay project, which is not reflected in the pavement ratings. Most of the traveled way on SR 77 is asphaltic concrete (AC). This type of pavement has a design life of approximately 10 years. After that time, the AC pavement is generally in need of milling and replacement. Based on the design life of pavement surfaces, it is expected that all pavement surfaces on SR 77 within the project limits will need to be rehabilitated within the next 20 years. Pavement rehabilitation should accompany widening projects identified in the PAG 2030 Regional Transportation Plan and ADOT Five Year Facilities and Construction Program. 6.7 AASHTO DESIGN STANDARDS The horizontal and vertical geometric deficiencies are defined in terms of the most recent standards or criteria set forth by the American Association of State Highway and Transportation Officials (AASHTO). The following design element deficiencies were identified: • Vertical curvature not meeting stopping sight distance criteria for given design speed of the roadways; • Horizontal curvature not falling within limits for maximum and minimum superelevation; • Horizontal curvature exceeding the recommended or maximum degree of curvature; and • Recommended maximum roadway grade of four percent is exceeded. To identify project deficiencies in the SR 77 corridor, project assessment reports prepared for segments in the corridor were reviewed. Several project assessments required an AASHTO Controlling Design Criteria Report, which gives a description of each design deficiency. Deficiencies identified in the corridor are summarized in Exhibits 6-14 and 6-15. SR 77/Oracle Road Multimodal Corridor Profile Study May 2007 Final Report Page 6-19
