Now we wait two years before we can use it. This underpass, which forms part of the Cambridgeshire Guided Busway route, was constructed by closing Long Road to motor traffic over the school summer holidays, whilst permitting pedestrians and cyclists to use a temporary bridge built for the construction workers themselves.
A huge hole was dug through the existing embankment and concrete ‘box’ segments laid to form the underpass. Although the guided bus route will use the existing bridge that formed part of the old Cambridge to Bedford rail line, there was no space for the maintenance road that will also form a new cycle route from Trumpington to the station, so the new underpass was required by the Transport and Works Act.
Of course we could have permitted cycling under here over 30 years ago, following the closure of the railway to Bedford, but the busway maintenance track will now continue under Hills Road, so access to the station area from the ‘Southern Fringe’ for cyclists and pedestrians will not require the crossing of any main roads.
The construction of the underpass for the busway at Hills Road will be a larger undertaking, and to avoid disruption of both these busy roads at the same time, the Long Road work has been done a year early.
