St. Augustine Bridge. — The history of the Fixed 

 Bridge movement is no doubt familiar to you all, and also 

 that an Act was obtained in the session of 1891, for the 

 bridge, archway, and filling the water space, at an estimated 

 cost of £23,500. The contract for this work was let a few 

 months since, and considerable progress has been made. The 

 first work was the erection of a temporary bridge to allow 

 of the removal of the Drawbridge and of the construction of 

 the southern half of the new bridge, on the completion of 

 which the traffic will be turned over it, and the remaining 

 half of the new bridge completed, the temporary bridge 

 being then removed. The roadway of the new bridge will 

 be about 75 feet wide, with foot pavements on each side 

 of 15 feet and 10 feet wide respectively. The archwa}- 

 for conveying the Frome to the Floating Harbour on the 

 south side of the new bridge has a clear span of 24 feet^ 

 The arch is of Catty brook brick, 2| bricks in thickness, 

 built in vertical bond, with a proper proportion of special 

 taper bricks. This arch is thicker than would be ordinarily 

 necessary for an arch of the span, but as buildings may 

 possibly be erected over it at some future time, and the 

 crown of the arch is very near the surface of the newly-made 

 ground, it was necessary to make it of extra strength. The 

 invert of the archway is formed of a layer of concrete dished 

 in the centre. The outer part of the archway towards the 

 Floating Harbour is of a span of 30 feet, to give a better 

 external appearance to the bridge. The face work of the 

 abutments and the curved wing-walls is of fitted rubble 

 below, and coursed rubble (in 12-inch courses) above water 

 level. The quoins, voussoirs, and strings, and other dressed 

 work are of red Wilderness stone from the Colchester- 

 Wemyss quarries. The new roadway will be of wood paving 

 on concrete. On the south side there will be an ornamental
