The Golden Ears Bridge is an $800 million project that will provide a vital new link between communities on the south side of the Fraser River - Langley and Surrey - and the north-side communities of Maple Ridge and Pitt Meadows. The curved part of the 199A Viaduct is a segmental, haunched steel box girder bridge with 65 m – 82 m – 66 m – 55 m long continuous spans and a minimum radius of 130 m. Due to lifting equipment limitations the bridge was broken in 6 – 15 m long segments to be spliced on site.

The main span was erected as a progressive cantilever. Infinity Engineering Group Ltd. provided erection engineering support to the contractor for the steel erection. A staged slab casting sequence analysis was conducted and the steel box was checked for strength and stability during casting stages in accordance with the requirements of CAN/CSA-S6-06. The detailed design of the bridge was conducted by Mr. Prabhjeet Singh, P.Eng. and Dr. Matthias Schueller, P.Eng.  of Infinity Engineering during employment with Buckland & Taylor Ltd.
