Posted Bridge Load Limits

Request email notification when page changes E-Notify

There are several bridges in Montgomery County that have posted load limits. Bridges not posted with a weight limit are rated at the maximum legal load limit as per the Ohio Revised Code.

Unfortunately, the condition of our bridges is deteriorating faster than we can replace them with our limited funding.  As a result, we have had to put load limit restrictions on some of the bridges in Montgomery County in order to keep them open to the traveling public until they can be replaced.  Therefore, there are some bridges that will affect the routes that your drivers use that you need to be aware of and request you route around them. 


This map shows the maximum allowable loads (carrying capacity) for County maintained bridges.  For bridges on state routes or city streets, contact that agency individually.

Posted Bridge List available in PDF format

NOTE: This restricted bridge list/map 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 list/map make certain that they have the latest version. Montgomery 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 these documents. In all cases, the weight limit signs posted at Montgomery County bridges shall take precedence over this table and map.

Montgomery 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 difficulty, truckers are urged to consult a map and this table in planning or predetermining available routes for a particular vehicle and load.


Here is a sample regular load reduction signs we use:

  Weight Limits   

 Basically, the current signs, that are required the State of Ohio, show silhouettes for the Ohio legal loads, which are
 essentially generic trucks (based on the number of axles) and represent the truck load configurations below. 

 Ie 2f is 2 axles, 3f is 3 axles, 4 f, is four axles, 5c is semis with five axles.

          Weight Limit 10 TONS   For some of the bridges, we have put an overall tonnage limit no matter the type and size of vehicle and
 they look like this.

Legal Load Permit Map

This Map shows the maximum allowable loads (carrying capacity) for County maintained bridges. For bridges on state routes or city streets, contact that agency individually.

Hauling Permit applications will be reviewed upon submittal to ensure that the vehicle % Ohio Legal Load does not exceed the bridge's rated % Ohio Legal Load. Permits will not be issued allowing vehicles to cross-posted bridges or bridges that are rated less than the vehicle's % Ohio Legal Load unless a "Superload" application is completed and reviewed by the engineering staff.

Questions regarding Special Hauling permits and the map should be directed to the Montgomery County Engineer's Office. Additional information on Special Hauling permits can be found here.
