NHDOT Bridge Overweight Permit Review (BOPR)

This program, Bridge Overweight Permit Review (BOPR), is designed to enable overweight permit applicants to review the adequacy of State highway bridges for their specific overweight vehicle. Once the applicant inputs the axles weights and spacings for their specific vehicle, the computer program reviews the effect of the proposed load configuration and compares it to the current rated capacity of all State bridges. The output provides the applicant with a file (which can be viewed or printed) listing each State bridge and indicating whether or not it is "OK TO CROSS" the bridge with the proposed load. A Google Earth map is also provided that depicts all State bridges and displays pertinent bridge data and review results ("OK TO CROSS", "NHDOT REVIEW REQUIRED", etc.). The output files and maps also list and display all municipal bridges and include the note "MUNICIPAL REVIEW REQUIRED", since each municipality is responsible for their specific bridges.
