A recently rediscovered list of leases from the 17th century provided a great deal of information, including the size and location of the 124 houses, the chapel, the gate and the drawbridge tower. By 1710, most of the houses on the bridge had been rebuilt in the Restoration style and in order to widen the roadway to , the new houses were built overhanging the river supported by wooden girders and struts which hid the tops of the arches. In 1722 congestion was becoming so serious that the Lord Mayor decreed that "all carts, coaches and other carriages coming out of Southwark into this City do keep all along the west side of the said bridge: and all carts and coaches going out of the City do keep along the east side of the said bridge." This has been suggested as one possible origin for the practice of traffic in Britain driving on the left.
