In an effort to address what it says is an ongoing problem with trucks getting stuck under a railroad overpass, the Maryland State Highway Administration is implementing a new truck restriction on a section of MD 75 (Green Valley Road) near Monrovia in Frederick County, just south of I-75.

Starting July 18, commercial vehicles over 48 feet long or over 102 inches wide will be restricted from using MD 75 between MD 80 (Fingerboard Road) and West Baldwin Road. Violations of the restriction will carry a fine of up to $500. 

Trucks that exceed the 48-foot length and 102-inch width would also be too tall for the bridge clearance of 12 feet, 6 inches. Signs about the restriction will be posted on MD 75 as well as along MD 355, MD 80 and the I-70 ramps to MD 75. 

“Despite the existing low-clearance warning signs, we are continuing to have problems with trucks that are too large attempting to use this route and becoming wedged under the railroad bridge,” said SHA District Engineer David Coyne. “We hope the new restriction and additional signs will help get truck drivers’ attention and make it easier for them to determine if their vehicles are too large.” 

The SHA says problems with stuck trucks have worsened since a Costco Distribution Depot opened on Intercoastal Drive off West Baldwin Road in Monrovia.
