What a highway authority wants in a construction traffic plan
A construction traffic management plan is read by a highway engineer checking routes, mud and pedestrian safety. Here is what to put in it and what gets it returned.
A construction traffic management plan is judged by one person, and that person is the highway authority's development control engineer. They are not reading it for design quality. They are checking whether lorries can reach the site without damaging the network, whether mud will end up on the carriageway, and whether pedestrians stay safe while it happens. Write the plan for that reader and it gets signed off. Write it as a generic method statement and it comes back.
Construction traffic management plan contents are rarely specified in the condition itself. The wording usually says the plan shall include details of parking, loading, storage and wheel cleaning, which leaves the rest to you.
When the plan is required and at what stage
Most CTMPs are secured by a pre-commencement condition, so nothing can lawfully start on site until the plan is approved in writing. Since the Neighbourhood Planning Act 2017 inserted section 100ZA into the Town and Country Planning Act 1990, the authority has to obtain the applicant's written agreement to a pre-commencement condition before imposing it, which gives you a moment to negotiate the trigger.
Use that moment. A condition triggered by the start of development stops everything, including site set up. A condition triggered by the start of above ground works lets you fence, strip and install the access under an approved advance plan.
Allow eight weeks for determination of the discharge application and assume the highway engineer will comment once and then go quiet for a fortnight. The application fee for discharging conditions is set nationally and indexed annually, so check the current schedule before you budget.
Where the site also needs a wider construction management plan covering noise, dust and working hours, submit the two together. A construction management plan and a traffic plan that contradict each other on working hours is the fastest route to a refusal of both.
Routing and getting the authority to agree it
The routing section should show the agreed route from the strategic road network to the site on a plan, with the direction of travel marked and any prohibited movements shown. Engineers want to see that lorries are kept off residential distributor roads, away from school frontages at opening and closing times, and off any road with a weight restriction.
Name the restrictions you have checked. Weak bridges, width restrictions, low bridges, environmental weight limits and 7.5 tonne zones all appear on the local traffic regulation order register, and an engineer who can see you have looked treats the rest of the document more generously.
Include the mechanism for enforcing the route. In practice that means a route plan issued to every haulier, a clause in the subcontract, a signing in procedure at the gate, and a named contact for complaints. Section 59 of the Highways Act 1980 lets the authority recover the cost of extraordinary damage caused by heavy traffic, so a joint condition survey of the route before works start protects both sides.
Access, wheel washing and keeping the road clean
The site access is the part the engineer will look at first. Show visibility splays for the construction access, including any temporary access that differs from the permanent one, and confirm they can be maintained with hoarding in place. Where the access crosses a footway, a vehicle crossing under section 184 of the Highways Act 1980 has to be constructed to the authority's specification, and that is a separate consent with its own lead time. Our note on temporary construction accesses and conditions covers the detail of getting one approved.
Wheel washing has to be proportionate. A drive through wheel wash with recirculating water suits a site moving spoil for weeks. A jet wash and hardstanding suits a two plot infill. What the engineer will not accept is a promise to clean wheels with no location shown for doing it and no drainage for the water.
State the road sweeping arrangement in terms that can be checked: a mechanical sweeper on call, attending within a stated time of any deposit, with a daily inspection of the first 50 metres of the route in each direction. Then keep the log.
Delivery hours, holding and the space problem
Delivery hours are normally conditioned separately, and the usual pattern is weekday working with restricted Saturday hours and nothing on Sundays or bank holidays. The traffic plan should confirm those hours and explain how deliveries are booked so that vehicles do not arrive outside them.
Holding is the hard part on tight urban sites. If there is no room to wait inside the site, the plan needs a booking system with named time slots and a nominated off site holding location, agreed with whoever owns it. Engineers reject plans that show lorries waiting on the highway, and they are right to.
Abnormal loads, crane lifts and concrete pours each need their own paragraph. A single pour can bring 20 mixers in a morning, and that is a temporary traffic management exercise rather than a delivery.
Worker parking and how to stop overspill
Construction worker parking causes more complaints than lorries do, because it lasts all day and it sits outside people's houses. The plan should state the expected workforce by phase, the number of spaces provided on site, and what happens at peak when the frame and the fit out overlap.
Realistic options are a compound area within the site, an agreed off site car park with a shuttle, a permit system with the parking authority, or a genuine travel plan for the workforce with transport to a park and ride. Saying that operatives will be encouraged to car share is not a plan.
Where the surrounding streets are controlled, agree in advance whether contractors can buy visitor permits, because unilateral permit use will exhaust the residents' allocation within a week. Where they are uncontrolled, the parking standards and survey evidence approach used for operational parking works just as well for construction stress.
Pedestrian safety and temporary closures
Anyone walking past the site is the person most at risk, so treat this section as the safety case rather than an afterthought. Show the pedestrian route past the site on a plan with dimensions, and keep a minimum usable footway width wherever possible.
Where the footway has to close, a temporary closure under the Road Traffic Regulation Act 1984 takes time to arrange, and the diversion route must be step free and lit. Show it. Where a hoarding or scaffold sits on the highway, a licence under sections 169 to 172 of the Highways Act 1980 is required, and the authority will want to see the gantry detail.
Banksman control at the gate, a stop and go system for reversing, and a prohibition on reversing from the highway into the site are the three measures engineers look for. Add the school liaison arrangement where a school lies on the route, including a ban on heavy vehicle movements during the arrival and departure windows.
Getting the condition discharged first time
The plans that go through without comment share four habits. They are drawing led, with the routing, access, parking, storage and pedestrian arrangements shown on a plan rather than described. They name the responsible person and a telephone number for complaints. They reference the Construction (Design and Management) Regulations 2015 duties without pretending planning and health and safety are the same regime. And they are specific about phases, because a plan that suits demolition rarely suits fit out.
Send a draft to the highway engineer informally before you submit the discharge application. Most will read it, and the comments you get back are the comments that would otherwise have cost you six weeks.
This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
When does a construction traffic management plan have to be approved?
Normally before development starts, because the plan is secured by a pre-commencement condition. Since section 100ZA of the Town and Country Planning Act 1990 came into force, the authority needs the applicant's written agreement to a pre-commencement condition, which is the point to negotiate a later trigger such as above ground works.
What is the difference between a construction traffic plan and a construction management plan?
The traffic plan covers routing, site access, wheel washing, deliveries, worker parking and pedestrian safety, and is assessed by the highway authority. The construction management plan covers hours of work, noise, dust, waste and neighbour liaison, and is assessed by environmental health. Submit them together so they agree with each other.
Do I need a separate consent for a temporary site access?
Usually yes. A vehicle crossing over a footway is constructed under section 184 of the Highways Act 1980 to the authority's specification, and a hoarding or scaffold on the highway needs a licence under sections 169 to 172. Both are separate from the planning condition and have their own lead times.
How should worker parking be dealt with in the plan?
State the expected workforce by phase, the spaces provided on site and the arrangement at peak when trades overlap. Credible options are an on site compound, an agreed off site car park with a shuttle, or a permit arrangement with the parking authority. Encouraging car sharing without numbers is not accepted.
Can the council recover the cost of road damage caused by construction traffic?
Section 59 of the Highways Act 1980 allows a highway authority to recover the cost of excess maintenance where extraordinary traffic has damaged a road. A joint condition survey of the agreed route before works start, repeated afterwards, protects the developer as much as the authority.
