One kilometre to the north is the B4265 road which connects Barry to Bridgend, via Llantwit Major and St Brides Major. Cardiff Airport is to the northeast. From the crossroads at the 14th-century Blue Anchor Inn, Well Road drops down a short steep hill to pass under an arched bridge carrying the double track Vale of Glamorgan line and extended in 1958 to carry new double tracks to Aberthaw "A" and "B" power stations. To the east from the crossroads, Port Road, a narrow lane, leads uphill to a farm group (Upper House Farm) and then passes over Aberthaw Cement Work's tunnel-connected extensive blue lias limestone quarries and on to some woodland at the hamlet of Fonmon, with alternative unclassified road access to Fontygary and Rhoose or to the B4265, passing Fonmon Castle.
