|Route outline (key)|
The A4094 is a relatively short A-road in the Home Counties.
The road starts at a roundabout on the A4 to the east of Maidenhead town centre. The road heads north, soon reaching the bank of the River Thames and following it to Boulter's Lock. Road and river then diverge and the road continues through the residential area, finally reaching open country.
After crossing Wildbrook Common, owned by the National Trust, the road reaches the affluent village of Cookham. The B4447 is met here, after which we cross the River Thames at a narrow bridge with flow controlled by traffic lights. The first building on the far side appears to be an old toll house but the bridge is now free to cross. Continuing north, there is a brief rural section before we enter Bourne End and cross one of many rivers in England called the Wye. Shortly the road splits. The road ahead, a spur, continues past the station (now a terminus although there was once presumably a level crossing here) to end at a mini-roundabout on the A4155. However, the mainline TOTSOs right to meet the A4155 at a triangular junction where it has to TOTSO right a second time.
We continue almost due eastwards into Cores End where we turn left at a roundabout to regain our northward route. The road continues alongside the River Wye, following a semi-rural route through Wooburn into Wooburn Green. Presently we go through an industrial estate to reach a roundabout under the M40 flyover. The road goes under the motorway and ends at the next roundabout on the A40. There are also east-facing sliproads from here to the motorway, making the roundabout part of M40 J3.
The A4094 came into existence in the mid-1920s when that part of the B3028 north of the A4 was upgraded to Class I status. Initially the road's northern end was on the A32 in Bourne End; it appears that the spur was in existence from the beginning although only the western branch was part of the B3028.
When the A32 was cut back in 1935 the A4094 took on its route from Bourne End to Loudwater and the A40. The road originally entered Loudwater along Boundary Road and Station Road and gained its current route to provide easier access to the M40.
