SHORT SPAN BRIDGES POSE CHALLENGES, SOLUTIONS

This article briefly reviews some of the most significant short span bridge projects and products in 1991. It is described how New York Department of Transportation chose steel for short spans. Of all bids received in response to full-steel and full-concrete design alternatives, steel won over concrete for all of four bridges. It is also described how in North Dakota, two new precast, post-tensioned reinforced concrete box culverts were placed in 3 days. In New Hampshire the first precast concrete modular bridge to be installed in the state is nearing its first year of service. It is described how multi-plate box culverts are designed for fast econimical bridge replacement. It is noted that real-time warnings are needed to prevent bridge failures due to scour. In Alaska, water and radio expertise is being combined to develop such real-time warnings.
