 " Account of the Victoria Bridge, erected across the riecr Wear, on the 

 line of the Durham Junction Hallway." Bv David Brcmner, Associate 

 lust. C. E. 



The district through which the Durham Junction Railway passes, for the 

 purpose of completing the connexion between the city of Durham, with the 

 towns of Newcastle, South Shields, and Sunderland, is extensively under- 

 mined by coal-workings, and great caution was requisite in the selection of a 

 spot which suited the level of the railway, and where a foundation could be 

 formed sufficiently sound to support such a structure as the bridge described 

 in the paper. The advice of Messrs. Walker and Burges was therefore 

 sought by Mr. Harrison, the engineer of the line, and their design was 

 adopted ; but subsequently several alterations were made, either to favour 

 the locality or from motives of economy. 



The bridge is 810 feet 9 inches long, and 21 feet wide, between the para- 

 pets. It is, with the exception of the quoins of the main arches, built of 

 freestone, from the Pensher quarries ; there arc three semicircular arches, of 

 Ml feet, 100 feet, and CO feet span respectively, a centre arch of 160 feet
