Custom cast steel wye nodes improve fatigue performance and enhance aesthetics of bridge

The Boston Esplanade Pedestrian Bridge is proposed as part of the master plan to restore the iconic 1908 Longfellow Bridge across the Charles River between Boston and Cambridge. The existing, obsolete pedestrian bridge next to the historic bridge will be replaced with a wider, ADA compliant bridge that will better complement the arches of the historic structure. The old and new pedestrian bridges span Storrow Drive, connecting from near Charles/MGH (MBTA station) to the Charles River Esplanade near the Longfellow Bridge.

The new bridge deck arch will be contemporary in appearance and very transparent, in order to not obstruct views of the historic Longfellow Bridge, the river, and parkland. The slender main steel arch span will be on the order of 222 feet (68 m) long. The approach ramps will appear to float over the landscape before landing next to the river.

The approach piers will be fitted with cast steel wye nodes engineered and supplied by CAST CONNEX. The wye nodes improve the fatigue performance of the pier connections and provide the approach spans with a unique aesthetic that follows a similar architectural language as the main span.
