A337 road Wikipedia
The A337 begins at junction 1 of the M27 motorway near Cadnam. It heads south through the New Forest to the large village of Lyndhurst. On account of the A337 being one of only a few main roads into the New Forest, it is frequently congested. In Lyndhurst the A337 meets the A35 road, and rings Lyndhurst village centre as a large roundabout. It continues south through the village of Brockenhurst, where it crosses the South Western Main Line at a level crossing, to the town of Lymington. In Lymington the A337 avoids the town centre, and heads west through Everton and Downton to the town of New Milton. It crosses the border into Dorset, travels through Highcliffe High Street and terminates at a roundabout with the A35 road in Christchurch.
