Brooklyn Bridge deck replaced at night
Article Abstract:
Work to rehabilitate the deck of the Brooklyn Bridge has been accelerated with construction crews working each night to replace the deck before it reaches the end of its useful life. The 34-million project requires the workers to conduct activities on platforms suspended beneath the bridge while replacing 60-ft long sections of the 1,596-ft main span each evening. About 400 cracked floor beams will be replaced, aside from other repairs. The crews are being provided a $45,000 per night incentive for early completion of the deck.

Coronado bridge undergoes second seismic upgrade
Article Abstract:
The San Diego-Coronado Bay Bridge in California is undergoing a seismic upgrade program. The $95 million project, which was designed by the California Dept of Transportation, T.Y. Lin International/McDaniel and J. Muller International, focuses on the strengthening of piers and addition of seismic isolator equipment. Engineers will place 200 to 400 mm post-tensioned reinforced concrete to pier caps. They will also encase the piers with concrete that extends 8.5 m down from the retrofitted caps.
