Less than two years after beginning construction, the new South Norfolk Jordan Bridge is open to traffic. As tall as a 17-story building, this modern bridge was constructed quickly using 856 precast concrete segments to p ro v i d e a n i m p o r t a n t c o m m u n i t y transportation link across the Elizabeth R i v e r b e t w e e n C h e s a p e a k e a n d Portsmouth, Va. The previous Jordan Bridge, a steel lift span, was closed to traffic by the City of Chesapeake after being rated structurally deficient. Removing this link from the regional transportation n e t w o r k i n c r e a s e d c o n g e s t i o n t h ro u g h o u t t h e a re a . T h e S o u t h Norfolk Jordan Bridge restores the connection, relieving congestion and providing added benefits to enhance the quality of life for the surrounding communities. In addition, the bridge project was accomplished using 100% private funding without the use of any local, state, or federal funding. The new bridge eliminates the lift span over the shipping channel and an at-grade active railroad crossing. The bridge also crosses local roads with long spans, allowing for the continuous flow of all vehicular and pedestrian traffic on top of the bridge while ships, trains, and other vehicles pass below. One of the challenges of replacing a lift span bridge in this location with a high-level fixed span and pedestrian friendly bridge was establishing the bridge geometry. The site constraints i n c l u d e d c l e a r a n c e r e q u i r e m e n t s over the river for navigation, railroad easements on both sides of the river, and existing tie-in points to surface s t re e t s .
