Bridge bent and ground movement update
Posted January 07, 2011
As we first reported in March, 2010 and updated in June and November, we have been monitoring for ground movement at several bridge locations within the project boundary after two bridge columns were found to have moved out-of-plumb.
In December, we were notified by our contractor that additional movement was detected in the area of the
We are now working to independently verify how much movement there has been and what the significance of the movement is.
We have installed additional instruments to monitor the landslide areas.
We hope to have enough data by early spring so the contractor can make a decision on how to respond to the movement. At that time, we hope to have a better estimate on when bridge construction can restart, how much it will cost and when we might complete the project.
When construction begins again, we will have about one season of work left to complete the project. Some of that work includes:
- 100,000 cubic yards of material to be excavated
- 4 bridges to complete
- Paving the remaining 50 percent of new alignment (About half of it was paved in 2010)
- Planting vegetation in the disturbed soil areas
