UPDATE 2PM: Mt CROSBY Rd was reopened at Colleges Crossing on Tuesday.
The scaling back of releases from Wivenhoe Dam resulted in the Brisbane River dropping back below road level by early morning, with council and Main Roads conducting checks before officially opening the road in the early afternoon.
The busy river crossing had been closed since Saturday morning, following significant inflows into the dams.
Ipswich City Council is expected to reopen Colleges Crossing park later in the week, following a clean-up effort.
9AM: Mt Crosby Rd at Colleges Crossing remains closed this morning, however the Brisbane River has dropped back below road level.
Ipswich City Council and Main Roads will have to assess the bridge before reopening it, however the QT understands the crossing could be open by this afternoon.
Motorists are advised to use an alternative route until further notice.
6AM: News that Colleges Crossing could be reopened as early as this afternoon will be welcomed by the hundreds of motorists who were late for work yesterday morning.
In a chaotic morning on Mt Crosby Rd, Ipswich-bound cars were backed up for several kilometres as they queued to get over the single-lane Mt Crosby Weir crossing.
Due to the nine-tonne weight restriction on the only remaining Brisbane River crossing in the vicinity, several school buses had to be turned away.

Southern Cross buses spokesman Nat Weeden said students from schools on both sides of the river had to be taken via the Centenary Highway, causing significant, but unavoidable, delays.
Authorities released 136,000 mega litres from Wivenhoe as of 1pm yesterday, hoping to reduce the amount of time that Colleges Crossing had to remain closed during the working week.
An Seqwater spokeswoman said Kholo Bridge was reopened just after midday yesterday, while Burtons Bridge would be reopened by this morning.
Seqwater CEO Peter Dennis said Twin Bridges, Savages Crossing and Colleges Crossing were expected to reopen later today.
"Based on the inflow volumes from the rainfall event, releases will likely occur from Wivenhoe Dam until Tuesday," Mr Dennis said.
"A very small fraction of the flood storage compartment of Wivenhoe Dam is being used to store floodwater inflows. The vast majority of Wivenhoe's flood storage compartment and the full flood storage compartment of Somerset Dam remain available."
As of 10am yesterday, Wivenhoe Dam was at just over 100% of its full supply capacity.
The dam releases provided an early test of the new flood resistant structures put in place at Colleges Crossing park last year.
Mayor Paul Pisasale said that with the water already starting to subside, initial inspections of the park indicated minimal water damage. The facilities will be hosed down and should be reopened later this week.
