SOUTH END RIVER ROAD LYME NH CLOSED TO THRU TRAFFIC
Effective October 9, 2015 there will be NO THRU TRAFFIC on the south end of River Road by order of the Select Board, Town of Lyme NH
Based on advice from CLD Consulting Engineers & Willis Geotechnical Engineer information and information from Town Counsel the Board has voted to close the section of River Road at the “slump”, this is approximately 2/10th of a mile south of the East Thetford Road intersection.
The Select board regrets having to close the south end of River Road but with 3 engineering firms and our attorneys telling us to close the road immediately, we really had no other option. The problem is the instability of the soils under the road and the very real potential for a catastrophic bank and road failure. Vibration from vehicle traffic is a major factor in increasing the probability of a catastrophic failure.
We are and have been pushing hard for several months for a feasible solution. Possible fixes include exposing the ledge to the east side of the road and blasting a two lane shelf into the ledge. As you can imagine this would be a very costly and a difficult challenge to accomplish. The second option is to reroute the road and put it to the east of the ledge and either bring it back down to River Road or out to the East Thetford Road. Another very costly but less challenging solution.
We should have a proposal for the remaining exploratory work needed on the ledge by Friday 10/9/15. Once we have approval from the land owner to access the property, the work will start immediately. We have expressed our need to have an answer as to which solution to pursue within the next couple of months. How soon we can open the road again will depend on finding the right solution and being able to fund the project. Realistically and optimistically we are looking at a minimum of a year.
Again, we truly regret having to take this action and appreciate your patience and understanding.
The Select Board
