Two busy Lincoln roads will be closed during the October half term week while Anglian Water carries out improvement works.
The works, which are aimed at reducing the chances of burst water mains, will be carried out with the Highways Agency.
Disruption on residents and road users will be kept to a minimum.
From 7pm on Saturday, October 25 until 6am on Monday, October 27 the southbound lane of Broadgate (The A15) will be closed from the junction of Monks Road whilst several old valves and manhole covers are replaced.
Further work will take place at the junction of Bargate and the High Street. This junction will be closed from Monday, October 27 until Friday, October 31 while a Pressure Reducing Valve is fitted.
Advance warning signs will be set up to alert customers to the coming work and diversion routes will be clearly signposted.
Antony Innes, from Anglian Water, said: “We know this work will cause disruption and we’re sorry for that. However, we hope customers will understand the long term benefit which it will bring.
“These two projects have been designed to significantly reduce the chances of burst water mains and leaks across the City’s network of pipes.
“By working closely with the Highways Agency to carefully plan the work we’re confident we can keep inconvenience to a minimum.
“To make sure residents in the Bargate area can still use the roads as normal we will be cancelling the one-way system and allowing two-way traffic along Tealby Street and Sidney Street during the work, but there will be now impact on the High Street itself.”
