Thank you for voicing your concerns.
As I attempted to explain in my article, the detour routes are vague because closure times are only intermittent and are subject to change.
I reached out to Trent Long, who presented the plan to the BoC, and asked that he respond to your comments. Below is his response:
"Thank you for your comments. The closures along Islands Highway will occur as the load is moved from Half Moon Marina to its destination at Firth Rixson’s facility in Tradeport East. The closures will begin on April 9, 2013. The timing of the closures will depend on several variables such as high tide, loading of the movement equipment at the marina, un-loading of the movement equipment at Firth Rixson, return of the movement equipment to the marina, etc. Generally the moves will occur every other day. In order to safely move the loads and minimize the impact to the traveling public, the moves will occur between the hours of 9:00 a.m. and 4:00 p.m. This should be after the school buses pick-up in the morning. The intent is to be off of Islands Highway when the buses return in the afternoon. The move will be accompanied by personnel from the Sheriff’s office. In case of an emergency the movement party will be notified and emergency vehicles will be allowed to pass.
The move has been permitted through the Georgia Department of Transportation. This permit included a 'Traffic Control and Movement Plan' as well as an in depth inspection of the current conditions of the roadways, culvert/bridge crossings and other obstacles. After the move is completed, the infrastructure will be inspected once again to determine if any damage has occurred. The permit does include a bond for damages. For your convenience I have posted a copy of the 'Traffic Control and Movement Plan' on our website at www.trlongeng.com. It is located at the bottom of our home page.
