T.Y. Lin International (TYLI) provided complete design services for the Pedestrian Overpass at University Metrorail Station in Coral Gables, Florida. The pedestrian bridge spans the busy U.S. 1 Corridor and provides an important link between the adjacent University Metrorail Station and the residential and business neighborhoods of Coral Gables and the University of Miami campus.
As Lead Designer for the Pedestrian Overpass, TYLI’s scope of work included design services for structural, mechanical, electrical, and civil engineering, architecture, surveying, right-of-way issues, soils investigation, utility identification and relocation, lighting, and maintenance of traffic.
The initial conceptual study phase of the project included bridge design, public involvement activities, construction documents, technical specifications, and preparation of the engineer's estimate of probable construction cost. TYLI held architectural concept coordination meetings with the lead agency, Miami-Dade County Department of Transportation and Public Works, and the City of Coral Gables to develop and receive approval on the details of the bridge supports and special design features integrated into the 125-foot-long structure.
Public safety remained a critical concern throughout all phases of the project, as the heavily trafficked U.S. 1/Mariposa Court intersection had been the site of a number of pedestrian fatalities or injuries.
- TYLI’s context-sensitive design took into consideration factors such as quality of life, sustainability, the cultural environment, and architectural styles.
- The elevator towers are clad in local fossilized limestone and the steel truss is clad in a series of perforated metal fins that constantly change angles to create a flowing wave form.
- TYLI designed the signature wave form to draw pedestrians and bicyclists to use the Pedestrian Overpass, keeping them safely off the busy, six-lane highway below.
- Elevators and bike-friendly stairs with a runnel allow easy access from both sides of U.S. 1.
