Hungerford Bridge is at the southern terminus of the A400, where traffic meets the Victoria Embankment and Cycle Superhighway 3.The Archway Tower, at the northern end of the A400
After Warren Street station, the A400 becomes a dual carriageway, part-way along Hampstead Road, as it passes through Somers Town. Hampstead Road's northern terminus is at Mornington Crescent tube station, and northbound A400 traffic travels along Camden High Street to the Britannia Junction. At the Britannia Junction, the A400 bears north-east onto Kentish Town Road. Camden High Street becomes the A502 towards Hampstead, whilst traffic may turn right onto the A503 (Camden Road).
Southbound traffic through Camden Town leaves Kentish Town Road near Camden Gardens. Traffic travels south along Camden Street, along which it meets the A503 (Camden Road) and the A4200 (Eversholt Street). Southbound traffic joins Hampstead Road to the south of Mornington Crescent tube station.
Continuing north, the A400 passes through Kentish Town. It then continues along Fortess Road towards Tufnell Park.
Air pollution along the A400 varies. Air pollution is monitored by the City of Westminster, the London Borough of Camden, and the London Borough of Islington. Levels of Nitrogen dioxide (NO2) sometimes exceed the Air Quality Objective, set by the UK Department for Environment, Food, and Rural Affairs (Defra) at 40 micrograms per metres cubed (μg/m3). Exposure to high levels of NO2 can lead to respiratory problems, and the gases sometimes inflame the lining of the lungs, reducing immunity to lung infections.
In the City of Westminster, there is a nearby NO2 monitoring point entitled Oxford Street East. In 2018, levels of NO2 failed to meet the Air Quality Objective, with the monitoring point recording an annual mean of 76 μg/m^3.[5]
In the London Borough of Camden, levels of NO2 are monitored in several locations in close proximity to the A400.[6] Results from 2018 include:
Hampstead Road used to run north to Hampstead, but has been renamed everywhere north of Mornington Crescent. Nonetheless, it still gave its name to Hampstead Road Locks and the original name of Primrose Hill railway station, which are both on the former part of Hampstead Road now called Chalk Farm Road.
Numbers 261–263,[8] the Prince of Wales pub at number 119,[9] Mornington Crescent tube station,[10] and the statue of Richard Cobden are all grade II listed buildings.[11]
Camden High Street

Camden High Street is a short stretch of road (about 900m long, mostly forming part of the A400) in Camden Town, in north-northwest London. It is part of the route from central London to Hampstead. It is the local high street and features major music venues at either end (KOKO, the former Camden Palace, at the southern end and the bridge over Regent's Canal at the northern end).
It is a one-way street only allowing vehicular traffic to travel northwards (southbound traffic uses the parallel Camden Street). Travelling north, traffic emerges from Hampstead Road (A400) into the High Street at the junction with Eversholt Street, by Mornington Crescent Underground station.
The northern extremity of Camden High Street lies at a bridge over Regent's Canal where the road turns Chalk Farm Road, into the southern end Kentish Town Road (where the A400 continues) and Camden Road. Camden Town Underground station is on the corner between Camden High Street and Kentish Town Road.
The street has a number of restaurants, bars and pubs. Junction Road is home to Archway Tower, a building whose appearance is divisive and there is debate as to whether it should be demolished.[12] However, the tower was remodelled in the 2010s with new cladding providing a more modern appearance.
