The normally busy B5062 between Shrewsbury and Telford remains closed at the mill bend between Roden and High Ercall after the high water levels caused damage to the bridge over the River Roden.
Work is underway at the site.
Telford & Wrekin council spokesman Russell Griffin spokesman said: "The road closure has been caused by flooding which resulted in the bridge walls failing. The closure will remain in place for most of the day while temporary stabilisation works are carried out. Hopefully we will be able to open the road back up again with traffic lights later today.
"However when water levels recede sufficiently we will have to implement another emergency road closure of three to four days to install a more robust solution that will last until the planned reconstruction works of the retaining walls are carried out early next year."
The council said that so far stabilising work was going well and as a result the road would stay closed for the rest of this week to allow the repair work to continue.
Chairman of Ercall Magna Parish Council, Councillor Ray Wickson said: "There has been adverse effects on residents. The main disruption for the community is actually the changes to the bus routes the number 16 and the 519. The Arriva service 519 is now running via Shawbury and timetable will have changed. Local motorists know the back roads and which lanes to use to get round.
"The road has been closed since Friday and the flooding affected approaches to the bridge."
The Environment Agency has eight alerts in place covering much of the county, including for the River Severn, River Sow and River Penk, the Severn Vyrnwy Confluence, the Tern and Perry Catchments, the River Dee Catchment and Upper Teme.
In Oswestry, the B5069 Gobowen Road is also closed due to flooding.
The forecast is that rain will clear throughout the morning leaving a mostly dry and cold day with plenty of sunshine.
River levels are expected to remain high throughout the day and said officers are closely monitoring the situation.
Oswestry, Chirk and Llangollen were the worst-affected, with other areas seeing just a dusting of the white stuff.
While the majority of the region remained safe, two people were treated for minor injuries after a crash on the A495 near Oswestry.
The two-car crash happened at just after 10.40am on Saturday, and firefighters and paramedics were sent to the scene.
It happened on the A495 near Porth-Y-Waen. Parts of the road were closed off while emergency services were in attendance, and traffic was moving slowly.
Unsettled week of weather ahead
The UK is in for another wet and unsettled week as communities already hit by flooding remain on high alert after heavy downpours left rivers swollen.
Met Office meteorologist Sophie Yeomans said a weather system moving across Europe will cause a “fair amount” of rainfall across England and Wales throughout the week.
“It is going to be an unsettled week in terms of rain,” she said.
Parts of the UK are still dealing with the aftermath of widespread flooding which hit towns across the Midlands and northern England on Thursday and Friday.
Several areas were deluged with one month’s worth of rain in a day and a woman died after being swept up in floodwaters.
The body of Annie Hall, the former High Sheriff of Derbyshire, was found in the River Derwent on Friday morning after she was engulfed by floodwater in Darley Dale, near Matlock.
