Spring Operations

Once the winter weather ends, Concord General Services’ Highway and Utilities Division begins spring operations for the City of Concord. 

Report A Concern

The City of Concord has partnered with SeeClickFix to launch a new reporting system. Use our new online web portal to report an issue (pothole, missed trash collection, illegal dumping, graffiti, damaged street sign, parking concern, snow plowing, and more).

Road Load Limits


Road damage occurs naturally during the transition from winter to spring due to the frequent thawing and freezing cycles. As the temperatures begin to warm each spring, the City of Concord implements load limits to protect road conditions pursuant to Code Ordinance 17-6-10. Fluctuating temperatures from winter to spring can cause roads to shift. Roads easily shift during the spring thaw, which occurs when any frozen ice underneath the asphalt begins to melt, typically in areas indicating frost heaves and recent potholes. Frost heaves are formed when snow and rain get through the cracks and freeze underneath the roads, expanding the road upwards. When temperatures warm, the ground thaws and the roads contract back down, causing breaks in the pavements, cracks, potholes, sinkholes, and weak road structures. Heavy weight on weakened roads can cause additional damage to the structure of a road. The amount of road damage is directly linked to how often a road is used and the weight of each load, especially if the road does not have a solid foundation. The temporary road load limits help to protect road conditions by minimizing additional stress on weakened road structures.

2021 Spring Road Load Limits

The City of Concord will be posting "No Trucking - Load Limit 9 Tons" signs on Monday, March 15, 2021 to protect roads from potential damage from heavy vehicles during the spring thaw.

Posted roads will prohibit trucking in excess of 9 tons. Road load limits will not affect the average car or truck, but will impact heavy construction vehicles and commercial trucking. Road load limits will continue as long as conditions require, but likely will remain in place until the end of March or early April depending on weather and road conditions. Limits will not be removed until all snow has melted and ditches are clear of any standing water. The City of Concord does not issue permits for drivers for spring load limits. Once road limits are posted, drivers can call Concord General Services at (603) 228-2737 to request for travel permissions if necessary for 1-2 loads before noon. We thank truckers for their cooperation.

Potholes & Road Damage

Filled Pot Hole Picture

Potholes are filled year round, but are fixed more often during late winter and early spring as road structures are weakened from changing temperatures. Freezing and thawing cycles cause the ground to shift, which can then cause cracks in the pavement. Moisture from snow and rain then get underneath the roads through the cracks. The water remains underneath the roads left to freeze since the frozen soil prevents the water from draining. As the water underneath the road freezes, the road expands upwards creating frost heaves. As temperatures warm, the ground thaws and roads contract back down and potholes are formed. Crews work in the spring to repair any road damages created during the spring thaw. Crews repair potholes by first cleaning out the debris in the hole, filling it in with either cold patch or hot mix, and then using a compactor to compress materials.

Hydrant Flushing

Hydrant Flush

Each spring, Concord General Services’ Highway and Utilities Division flushes City-owned hydrants as part of required routine maintenance to remove any sediment from water distribution pipes. This process maintains water quality, water clarity, and also checks for water pressure. Water customers may experience low water pressure and discolored water in their area during hydrant flushing. Residents should avoid doing laundry during their scheduled flushing time. If discoloration occurs, please run your tap water on cold until the water runs clear.
