Larimer County Bridge Weight Limits

The Engineering Department is responsible for ensuring that bridges incapable of supporting legal highway loads are properly posted. All Larimer County bridges are inspected every two years. The following table details the bridges which are posted as of July, 2015.

For information regarding these structures please contact the Engineering Department (970-498-5713).

DATE LAST UPDATED:    September, 2016

Larimer County's bridge posting program seeks to make known the safe load carrying capacity of structures which cannot presently withstand the maximum legal load permitted on the highway. The sign restrictions meet federal bridge inspection standards and requirements. To minimize inconvenience and difficulity, truckers are urged to consult a map and this table in planning or predetermining available routes for a particular vehicle and load.

NOTE: This restricted bridge list is not static. As bridges are replaced or rehabilitated, the load limit restrictions may be removed or changed. Also, as existing bridges deteriorate or are damaged, load limit restrictions may have to be placed upon them. It is imperative that all users of this table make certain that they have the latest version. Larimer County will make every effort to keep users informed of any changes but cannot accept responsibility or liability for any user not utilizing the latest version of this document. In all cases, with the possible exception of gross load posting as described below, the weight limit signs posted at Larimer County bridges shall take precedence over this table.

If the 'gross load' field shows a value, it indicates that the bridge is posted for a gross load only. If the 'truck type' fields also show values, it indicates that trucks over the gross load amount may safely cross the structure provided that the truck weight does not exceed the value given for the truck's axle configuration for Type II and Type III vehicles.
