According to WisDOT, work on the two temporary stabilization towers was completed over the weekend. The towers are a safety precaution. They are temporarily holding up pier 22 and allow workers to have access to the bridge decking.
The permanent fix includes driving four drill shafts more than 100 feet into the ground near the five piers that have showed signs of corrosion.
"We're probably about a week away from starting that 24/7 operation," said WisDOT Project Chief Brian Roper. "We have five piers with four drilled shafts each which, according to math class, tells us we have 20 of those drilled shafts to go ahead and produce. So while it may seem that the progress at this point is a little bit slow, our contractor is getting their feet on the ground here and we expect to see them ramp up within the coming week."
WisDOT said the project is on schedule and officials expect the bridge to re-open in mid-January.
A report about the investigation into the sinking of the bridge should be made available sometime next month.
