|Route outline (key)|
The B4078 is a rural B-road on the edge of the Cotswolds.
It starts on the B4632 (former A46) Winchcombe High Street. The High Street is narrow and possibly one of the reasons why the A46 was downgraded in this area. The B4078 heads north along North Street, which is just as narrow, before it TOTSOs right to go along Greet Road.
Greet is the next village but home of Winchcombe station on the preserved Gloucestershire Warwickshire Railway. The road crosses a bridge over the line before skirting a hill and reaching a crossroads on the B4077 - that road has priority. Having crossed the B4077 Alderton Hill is seen to the west but the B4078 is flat and with few buildings adjacent. Soon, however, the county boundary is crossed and then the road enters Sedgeberrow.
The road runs through the village before reaching a T-junction. The road originally ended here on the A435 but a bypass has since been built. The B4077 therefore TOTSOs right (although turning left will also take you to the bypass) and ends a short distance further on on the bypass, now numbered A46.
