Engineers get the call from land, sea and air
Article Abstract:
The engineers of the InsideThorofare Bridge reconstruction project in Atlantic City, NJ, faced strict design citeria from different agencies and a critical bridge demolition phase. They had to keep two opposite lanes open even while the superstructure demolition took place close to the traffic in some areas. The mechanical and electrical systems of the bridge's bascule leaves were kept open at all times while the substructure demolition was done in phases. The new bridge features aunique system wherein bascule leaves alternate as double-leaf systems during normal operations.

Below Boston's new bridge: Foundations for the dramatic new Charles River Bridge in Boston had to straddle an active subway line just 9 ft below, and squeeze between other underground obstacles
Article Abstract:
The Charles River crossing bridge is planned to open to northbound traffic by July 2002. Its foundation design has been constrained by several factors, including the proximity to existing underground facilities, complex bedrock conditions and the requirement to allow for a future north-south underground rail link. The existing bridge also had to remain in service until the new one opens. The new bridge will have 10 lanes and will improve Boston's traffic flow.

Rapid redecking
Article Abstract:
A twenty-four-hour construction programme has been used to complete a 7000 square meter bridge deck replacement over twelve months before scheduled completion. The busy Thousand Islands bridge system in Ontario, Canada, consists of a steel grid roadway deck and is used by 4,000 cars, daily. The bridge's 102 suspension span deck panels were swapped in 62 nights. Phases of the construction project are described.
