This is a 100% final construction design plan set for the Armstrong Avenue Pedestrian Bridge project in Tustin, California, prepared by TYLIN International and approved by Kenny T. Nguyen, City Engineer, dated June 30, 2026. The comprehensive plans document specifications for a pedestrian bridge structure spanning Armstrong Avenue, including detailed structural, foundation, architectural, electrical, and landscape design components. The project involves a reinforced concrete bridge deck with integral girders supported by pile foundations (48-inch and 72-inch CIDH piles), two abutments with wingwalls, a central pier with diaphragms, elastomeric bearings, and pedestrian railings with timber assembly details. The design incorporates architectural features including landscape walls, planters with drainage systems, architectural deck treatments with staining limits, and an integrated lighting system with motion sensors, LED fixtures, and control systems distributed across the bridge span.

The technical specifications detail concrete strength requirements using Load and Resistance Factor Design (LRFD), reinforcing steel layouts for girders and foundations, bearing seat details, pedestrian joint armor, weep hole drainage provisions, and decorative elements such as monuments at bridge approaches. The electrical and lighting design comprises multiple fixture types (SS1 through SS4 classifications) with photometric calculations showing average illuminance of 5.51 foot-candles across the deck, motion-activated controls via radar sensors, and distributed driver enclosures at pier locations. Geotechnical boring logs indicate alluvium and clay soil conditions with groundwater encountered between 10 and 11 feet depth. The plans include a complete index of 61 drawing sheets covering foundation details, pier and abutment reinforcement, girder layouts, drainage systems, pedestrian railings, landscape walls, and comprehensive electrical specifications for the integrated lighting and control systems, all approved and executed with digital verification as of August 6, 2025.
