exit forming the junction with the A3102 to Melksham. It follows New Road and passes by the old coaching inn of the Lansdowne Strand. On the way out of Calne, the road goes along Curzon Street, and then to Chilvester Hill at the roundabout where the northern part of the A3102 splits off towards Lyneham. The A4 descends steeply before climbing again up Black Dog Hill past the Bowood House Estate. The old road used to pass through Derry Hill, but the New Road, as it is called at this point, indicates that the village was bypassed. There follows a steep descent to the junction with the A342 Devizes road and a right turn past the Lysley Arms towards Chippenham. On the outskirts of Chippenham is a large roundabout, where the A4 used to carry straight on down London Road and The Causeway into the town centre, which has since been pedestrianised. Most traffic turns left to go round the Pewsham Estate relief road called Pewsham Way, which is now the classified A4 route. After four roundabouts, the A4 turns left in a southerly direction at another roundabout. The route heads downhill over the River Avon on the Avenue La Fleche, named after one of Chippenham's twin towns, to the Bridge Centre roundabout. Chippenham to Bath (12.7 miles) The Bridge Centre roundabout forms a junction of the A4 with the A420 Bristol Road. The route heads over Rowden Hill past the Chippenham Community Hospital and down to the spot where musician Eddie Cochran was killed in a car crash on 17 April 1960. A plaque has been placed there in remembrance. From there it passes under the railway arch built by Isambard Kingdom Brunel in the 1830s and on to its junction with the A350. From this point onwards it regains its trunk road status and heads up Chequers Hill towards Corsham. The road passes through Pickwick, which used to be a village in its own right. Charles Dickens stayed at the Hare & Hounds Inn and used the village name for the title of his novel The Pickwick Papers. After a series of roundabouts the A4 continues uphill, past what used to be the Ministry of Defence Naval Operations site at Copenacre (now a housing development) before descending steeply to the village of Box. From the road the Box Tunnel, built as part of the Great Western Railway, can
