We have also completed the west side works on East Columbia up to and including Sherbrooke. Last week (Nov 15) we have completed ALL road excavations sub-base and base gravels and base paving. This was a big milestone for All Roads because for the last 3 months we have had a substantial grade difference at the crown of East Columbia due to the new design. This created issues for the vehicle traffic, as well as controlling of rain water, which we've had plenty due to a few atmospheric river events!
Now that it is all base paved the road drains and function as designed. Construction at the emergency entrance had its challenges as well. We had to maintain an entrance and exit at all times after working hours. We had to construct the entrance in sections and allow concrete to cure before removing the remainder of the driveway and completing the entrance. This was difficult to do as the new design was approximately 200 mm higher than the existing design!
So, there was a large grade difference in the middle of emergency that we had to get creative so it would function. If we get the weather we should be done the south side of east Columbia by the end of this month.
