Montgomery County Department of Transportation (MCDOT) has an industry-accepted, award winning system for analyzing the conditions of the pavement for all 5,200 lane miles of roadways within the County. This system is called Pavement Management and is founded by a numeric system referred to as Pavement Condition Index or PCI. MCDOT's Division of Highway Services (DHS) conducts this PCI survey on a biannual basis. This is a state-of-the-art process that uses high resolution cameras coupled with lasers mounted on slow moving vehicles (akin to Google) that accurately measures and records detailed pavement conditions. If the road requires immediate repairs, please see topics entitled "Road Repair" or "Potholes". If the road is a numbered route such as Rte. 355, 117, please contact the Maryland State Highway Administration at 301.513.7300.
