Tacoma Narrows toll canopy takes shape
Published: December 31, 2004
Crews are to place two large steel roof truss segments for the Tacoma Narrows Bridge's toll plazas next week. A 250t crane will hoist the trusses into position so that they can be welded to create a 40t roof structure, 34m long. The roof will shelter six manual toll booths. The suspension bridge is due to open in spring 2007, as a twin to the 1950 crossing which stands 56m to the north. The new US$849 million bridge will have a 853m main span and the structure has been designed to allow a second deck to be added if traffic continues to grow as predicted. |
