Construction

 Road. However, the ground here was soft, and Harrison was concerned that the mud would not be able to support the weight of the piers. Eventually, Thomas Telford found a drier area of land downstream, and the construction was moved to this site. In order to accommodate the move of the bridge, Wrexham Road was split into two, with one lane becoming a dead end, and the other turning to meet the bridge. The first stone of the bridge was laid by the Marquess of Westminster

 on 17 October 1832. The bridge was not completed however until November 1833, and a toll was imposed on the bridge to pay the £50,000 (£ as of ) construction costs, a large sum at the time. The toll was however harmful to trade in the city, and toll-fees were abolished in 1885, when maintenance was transferred to the Chester Corporation. However, Thomas Harrison never lived to see his bridge being completed, nor being opened by the Princess. He died in 1829, and the completion of the work was supervised by his pupil, William Cole.
