Spring Operations

Once the winter weather ends, Concord General Services’ Highway and Utilities Division begins spring operations for the City of Concord. 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. The spring thaw can cause potholes, sink holes, cracks, and road damage. Crews work in the spring to prevent and repair any road damages created during the spring thaw.

Use our request tracker to report any of the following concerns:

  • Potholes
  • Road Damage
  • Road Mark Fading
  • Barricade Request
  • Sink Hole
  • Blocked Catch Basin / Culvert
  • Paving Concern

Road Load Limits - 9 Tons


The City of Concord will begin posting "No Trucking - Load Limit 9 Tons" signs on Monday, March 25, 2019 to protect roads from potential damage from heavy vehicles during the spring thaw. The spring thaw refers to when the temperatures fluctuate and the roads begin to melt any ice frozen underneath the asphalt, typically in areas indicating frost heaves and recent potholes. Road damage naturally occurs this time of year from the frequent thawing and freezing cycles, but heavy weight on weakened roads can cause additional harm. 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 City of Concord is posting load limits set to 9 tons to protect streets from any potential damage from heavy vehicles. 

2019 Spring Road Load Postings

View the list below of where load limit signs will be posted for the 2019 spring season, starting March 25, 2019. Road weight restrictions will continue as long as conditions require, but will likely remain in place until the end of March or beginning of April depending on the weather and road conditions. Road load limits will not be removed until all snow has melted and ditches are clear of any standing water. The City of Concord does not provide permits for spring load limits, but drivers can call Concord General Services at (603) 228-2737 to request travel permissions if necessary for 1-2 loads before noon.

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.

2019 Hydrant Flushing

Hydrant flushing for the season has not yet started. Flushing is anticipated to occur near the end of April and will continue for several weeks in different areas of the city. Concord water customers should check back soon for hydrant flushing schedules to determine when flushing will occur in their area.

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 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. Please use the request tracker above if you would like to report a pothole.
