Work is to begin next week on installing new underground utility trenches as part of a £22m upgrade to a major route into Liverpool city centre.
Contractors, Osborne, are to start the latest phase of the Great Howard Street (A565) scheme on Tuesday, 18 September.
To allow for the works to be carried out the inbound lane, heading south to the city centre, will be closed for four weeks from the junction of Blackstone Street. The outbound lane will also be reduced to a single lane.
Motorists travelling in to Liverpool from Bootle will be guided by a series of road diversions at :
Millers Bridge (Balliol Road)
Drivers are guided to use the Stanley Road, Commercial Road and Vauxhall Road corridor into the city centre.
The utility works are timetabled to run until Friday, 19 October, but will be suspended from Thursday-Sunday, 4-7 October as the city hosts The Giants – a spectacular street theatre performance.
Councillor James Noakes, Cabinet member for Highways, said: “Great Howard Street is a critical arterial road for Liverpool connecting Bootle and Sefton to the city centre and its upgrade is vital to the development of the North Liverpool economy – not least the Ten Streets creativity district and the new cruise facilities.
“These utility works are a critical phase of the scheme and unfortunately the only way for our contractors to carry it out is to close off the city centre bound lanes over the next month. We know this will cause disruption to commuters but fortunately the area is serviced by other major roads and we have tried to ensure the impact is kept to a minimum with the works to be carried out in the shorted possible timeframe.”
