The B2177 is a B road in Hampshire, England a constituent country of the United Kingdom. It starts at the traffic light junction with the B2150 north and the B2150 east in Bedhampton (50.8555°N 1.0025°W) [B2177 road (eastern end)] and continues to the roundabout where a right turn takes the driver up onto the slopes of Portsdown Hill. It shortly crosses the A3(M) by a high road bridge and continues for some distance westwards on a mainly straight road past several Napoleonic era forts before turning north west, skirting the village of Southwick going through North Boarhunt before reaching Wickham.
