Since the opening of the DLR, Limehouse has become a well-used interchange for Essex and east London commuters who work in the Canary Wharf area, but the two viaducts remained separate, resulting in an awkward interchange between the DLR platforms and the National Rail platforms, as passengers had to pass down and then up flights of stairs. To remedy this, at least in part, a bridge was built to connect the westbound (London-bound) main line platform with the adjacent eastbound (Canary Wharf-bound) DLR platform. It was originally due for completion by the end of 2008, but was finally opened in November 2009. At the same time as the bridge was being built, other improvements were made, including readying the station for three-carriage operations on the DLR and the construction of an additional eastern entrance, with lifts and stairways for platform access.
