Brief Introduction

Deck-type panel bridges are normally two lanes, class 50 or higher bridges assembled to replace single-lane bridges. A deck-type panel bridge has the following advantages over a through-type bridge :

•   Roadway can be wider for passage of extra-wide vehicles.
•   Deck-type assembly allows greater side overhang of vehicles.
•   A lighter decking system can be used when the roadway is supported by trusses.
•   With some sloping banks, the span between abutments is shorter than in a through-type bridge, because bearings are set 5 feet (1.5 meters)   below road level.
•  Demolished piers need not be built Up to the level of the roadway.
•  There are no overhead restrictions.

A deck-type panel bridge has the following disadvantages:

• Excavation at abutments may be necessary because bearings are 5 feet (1.5 meters) below the roadway.
• It is more difficult to launch.
• It must be lowered 5 feet (1.5 meters) onto the bearings.
• Waterway clearance is decreased.
