The photograph features a bridge spanning a body of water. Trees appear on each side of the body of water. A very large piece of machinery is supported on two trailers and is crossing the bridge, with the help of numerous construction workers clothed with safety vests and hard hats.

Key Project Goals

Develop a National Bridge Traffic Database
Determine and quantify influence of trucks on bridge component performance
Develop protocols for collecting research quality bridge traffic data
Develop tools and products that bridge owners can use to manage and operate loading conditions on existing network of highway bridges

Project Contract Awarded

FHWA LTBP IDIQ Contractors submitted proposals for ‘proof of concept’ task order
Pennoni Associates awarded 2-year contract in November 2013

Project Details

Conduct literature review of WIM data collection systems
Identify best technologies for collecting necessary data
Identify best locations for data collection and # of sites
Develop protocols for collecting research quality bridge traffic data
Synthesize all findings and conduct workshop
Collect data for 2 years at select sites

The photograph on the left features a tractor trailer on top of a bridge with a large concrete structure on the bed of the truck. The words “Oversize Load” appear on a sign on the back of the trailer, and orange flags appear on the concrete structure and on the truck. A worker wearing an orange and yellow safety vest appears in the lower right portion of the photograph.

The photograph on the right shows a two lane bridge. There is a tractor trailer in the left lane. No traffic appears in the right lane. A sign appears to the right of the right lane. The sign reads "Weight Limit Reduced - Any Single Axle - 20,000 LBS - Any Tandem Axle - 34,000 LBS - Max Gross Weight - 80,000 LBS - Legal Axle Weights Only"
