Weight Restrictions For Added McHenry County Bridges

The Illinois Department of Transportation Bureau of Bridges and Structures Local Unit (IDOT BBS) has recently inspected and analyzed various bridges in McHenry County.  Inspections are accomplished on a routine basis and intermittently on all County Highway bridges throughout McHenry County.  IDOT sets the inspection interval. The McHenry County Division of Transportation (MCDOT) is responsible for overseeing these inspections and reporting them to the IDOT.  The following bridges will have the following weight limit restrictions placed on them (please see the attached location map for these structures):

County Bridges

The MCDOT will post North Union Road Bridge located in unincorporated Seneca Township, north of IL 176 over the Kishwaukee River at a weight limit of 12 Tons for all vehicles. This structure will be considered to be programmed in the Highway Improvement 5-Year Program next year for the engineering phases to replace it.

The MCDOT will also reduce the existing load posting on Deerpass Road Bridge located in unincorporated Seneca Township north of IL 176 over the Kishwaukee River Main Channel from a posting of from Legal Load Only to a restriction to 15 Tons for All Vehicles. The MCDOT is currently in Phase I preliminary engineering working towards the actual bridge replacement.  The duration of the reduced load posting is indefinite at this point in time; however, the bridge has been programmed for replacement in the McHenry County Division of Transportation’s Five Year Highway Improvement Program.

Township Bridges

The following township bridges will also be posted with restrictions:

Chemung Township - Oak Grove Road over Drainage Ditch located southwest of US 14 will be posted at 14 Tons for All Vehicles.

Greenwood Township - Jankowski Road over Branch of Nippersink Creek located west of Raycraft Road will be posted at 5 Tons for All Vehicles.  Plans for the replacement of the deck of this bridge are currently being engineered for the Greenwood Township Road District for construction later this year.  Once this project is complete, the load posting will be able to be removed on this bridge.

Hebron Township - O'Brien Road over Nippersink Creek located 1.5 mi west of IL 47 will be posted at 13 Tons for All Vehicles.  Drivers are reminded that IL 173 over the Nippersink Creek upstream of the O’Brien Road Bridge is being replaced under staged construction. 

Please use the designated staged construction route or call the MCDOT at 815.334.4980 to permit loads avoiding this construction zone. O’Brien Road is not a viable alternative route due to the weight limit restrictions on the bridge.
