Does the bridge have high average daily traffic (ADT) and/or high average daily truck traffic (ADTT), or is it over an existing high-traffic-volume highway?
The higher the daily traffic and particularly the daily truck traffic, the greater the safety concerns for the travelers and construction crews in the work zones. Also, traffic control costs and user delay costs can be much higher if traffic volumes are high. These safety concerns and costs can be significantly reduced by the use of prefabrication to reduce onsite construction time. • Is this project an emergency bridge replacement? Bridge replacements are either planned due to structural deficiency or functional obsolescence of an existing bridge, or emergencies due to catastrophic damage to an existing bridge. Emergency bridge replacements particularly benefit from the use of prefabricated systems because the existing bridge cannot be used and must be replaced in the least time possible in order to minimize traffic disruption. • Is the bridge an evacuation route, or over a railroad or navigable waterway? Repair or replacement of bridges on evacuation routes must be completed quickly
