The Ralph Wilson Park Bridge is being replaced to improve pedestrian and cyclist access to a waterfront park by the same name undergoing a US$20 million renovation in the city of Buffalo, about 30km south of Niagara Falls.
The 81m-long enclosed steel arch design was chosen through a community-based competition led by the Regional Institute of the University of Buffalo in early 2020. Schlaich bergermann partner (sbp) designed the distinct and optimised structure to reduce noise from the below road and rail traffic, improving user experience, while referencing Buffalo’s rich architectural and industrial heritage.
“The Interstate below had perhaps the largest impact on the arch bridge’s design,” explained Michael Stein, managing director of sbp. “First, we needed to design a bridge that would transport users safely across the roadway in an enjoyable manner. If we did our job correctly, you won’t even realize you’ve left the park when you’re on the bridge. A bonus is that the enclosed arch also frames views toward the park and Lake Erie beyond.”
The efficient arch system also facilitated prefabrication, allowing the project team to meet the requirement of installing the structure in a single night closure.
The bridge was manufactured by Cimolai and shipped from Italy in four sections earlier this year.
Contractor Gilbane Building Company installed the bridge in 12 hours on the evening of 5 to 6 October using two gantry cranes at each abutment and a 100t rough terrain assist crane on the roadway.
“This milestone marks the culmination of months of coordination, planning, and hard work from all teams involved, including our design partners and trade partners,” said Keith Neuscheler, senior project executive at Gilbane Building Company.
Finishing works are currently under way on site with crews pouring the deck, followed by installation of railings, handrails and LED lighting. The footbridge is expected to open in early 2026.
