As well as changes to bus stops there will also be lane closures as the ongoing water-pipes upgrade continues in Glasgow.
Work has begun at various points in Renfield Street, Renfrew Street and St Vincent Street as part of a £3.5million programme by Scottish Water.
The work is being carried out during a year-long plan to replace five miles of crumbling water mains in the city centre, which will improve services to thousands of properties and customers.
It will also help provide cleaner, fresher drinking water.
But it will affect almost every road from Renfrew Street in the north to Waterloo Street in the south and from West Nile Street in the east to Wellington Street in the west.
Scottish Water says the upgrade will reduce the risk of long-term bursts and inconvenience to customers, road users and pedestrians.
Most of the work will involve pulling heavy-duty plastic pipes through the existing pipe works, which are mainly cast iron.
Scottish Water says a small amount of the work will involve excavating roads to allow existing pipes to be removed and replaced.
Traffic management which is already in place –mainly with closures affecting lanes which are used for parking – will continue until early next week.
There will also be a temporary closure at St Vincent Street at its junction with West Nile Street and its junction with Renfield Street, which will be for two days from Sunday.
After that, it is planned that work will start in West George Street at the end of this month and will continue until around the middle of next month.Traffic management will be required and this is expected to involve a lane closure in West George Street from its junction with Wellington Street to its junction with Renfield Street.
Charlene McBride, Scottish Water's regional community manager, said: "Scottish Water and our contractors Farrans are doing everything possible to minimise any inconvenience caused by our improvement work and any road traffic measures required.
"We will continue to do so as the project progresses. The project is expected to be completed next summer.
"We thank customers, businesses and road users for their patience and co-operation and hope they appreciate that the long-term benefits of our work will far out-weigh any short-term inconvenience."
In January this year, a £1.8m project started to install seven pressure control valves to cut the number of bursts by better management of water pressure in the city's main water network. Utility companies have a statutory right under the New Roads and the Street Works Act 1991 to place, inspect, maintain, adjust, repair, alter, change position or renew apparatus that belongs to them.
GLASGOW City Council is aware of the work being done and is meeting regularly with Scottish Water as it goes on.
Meanwhile roadworks are due to disrupt traffic for up to eight weeks at the junction of Argyle Street, Jamaica Street and Union Street.
The northbound Jamaica Street bus lane will be closed between Midland Street and Argyle Street and lane restrictions will be in place on other surrounding roads.
The bus stop at The Goose pub in Union Street will be closed for the duration of the works.
Regular bus user Rhona Parker, 60, from Cardonald, said: "It's terrible,
"One minute one stop is closed and the next, it's another.
"You never know what's going to happen next."
These works will begin on Monday and could be in effect when the Christmas rush starts in December.
As of Sunday, West Nile Street will be closed at West George Street for two days, which is expected to cause further chaos.
A city council spokesman said: "We are carrying out a complete refurbishment of the junction as part of a £12m investment in our streets this year.
"The work has been scheduled to coincide with school holidays, when traffic levels are lower, and also to allow utilities access to the road before it is resurfaced – minimising future disruption for road users."
