A contemporary newspaper report on the opening of the railway from The Times described it as "...consisting of 42 arches each 30 feet wide and 97 feet high and built at a cost between £70,000 and £80,000. The masonry has all the appearance of great solidity..." As well it might as 159 years further on it still has all the appearance of great solidity!
This is the view of 10 of the 42 arches taken looking along Hertford Road.
