The current Flagler Memorial Bridge, which is over 70 years old and spans over the Lake Worth Lagoon, connects the town of Palm Beach and the city of West Palm Beach. A wider and higher bridge will replace the current low level (17 ft clearance at navigable channel) 4-lane bridge which is 2,299 ft long with a 115 ft rolling lift span. The alignment of the new 4 lane bridge will be located just south of the existing bridge and include a new rolling lift span with a 21 ft vertical clearance and 125 ft of horizontal clearance at the navigable channel. This $94M project is scheduled to be completed by 2015.

Historic markers will be incorporated into the replacement bridge to commemorate Henry Morrison Flagler’s contribution to the development of South Florida. The design of the new bridge will also integrate the historical significance of Henry Flagler and relocate the gateway pylons donated by Colonel Edward R. Bradley to the east abutment of the new bridge.

The Murray Morgan Bridge, designed by Hardesty & Hanover in 1913, carries 11th Street over the Thea Foss Waterway. The bridge has a total length of approximately 1,760 feet, and comprises three segments – the south approach, a multi-span steel girder structure built in 1913; the north approach, a multi-span concrete girder structure built in 1954 as a replacement to the original approach structure; and a three-span, steel through-truss main river section with a vertical-lift center span. The bridge was placed on the National Register of Historic Places in 1982.

The $47M Murray Morgan Bridge project will be highly visible for the City of Tacoma. PCL/H&H will work together to restore vehicular traffic to the bridge without load restrictions, while improving the operating and maintenance of the bridge. The project has a 2-year schedule for design through complete construction.
