The B7088 is a short link road across the River Tweed in Peeblesshire. Originally the river was crossed here by a ford which fell into disrepair in the second half of the 20th century. The bridge was built in the 1990s but the classification of the road seems to have come later; the number does not appear on maps or signs but does appear on the list of public roads published by the Scottish Borders Council.
The route turns off the A72 in the settlement of Horsbrugh Ford, named after the adjacent old river crossing which is no longer visible. It runs along Loverose Way, which follows the river upstream a short distance to a roundabout, providing access to a hotel and golf course. Here the route then turns left to cross the River Tweed, and is signed as the B7062 without brackets. Just upstream is an old railway bridge, now used for foot access to the golf course. After passing the old station (now Cardrona Village Store) on the right and more of the golf course on the left, the route reaches another roundabout where Cardrona village itself lies to the left. The B7088 turns right here, again signed as a spur of the B7062, and passes some modern flats, ending shortly afterwards at a T-junction on the actual B7062.
