A road junction at Orsett
The B188 links the village of Orsett in south Essex with the two A-roads that bypass it.
The B188 starts in Orsett Heath on the A1013 (former A13) and heads north. It goes under the Baker Street Interchange without connecting with either the A13 or A1089. It then reaches a crossroads at the Baker Street end of Orsett, where it TOTSOs right, as indicated by an elderly fingerpost.
Orsett proper is then passed through and the B188 TOTSOs again, this time to the left, at the east end of the High Street. The road then leaves the village and bears right to end on the A128 just north of Sticking Hill (which reaches the lofty height of 21 m).
