It took China 43 hours to build a bridge. It took Iowa 14 days to build a bridge. It took Medford, Mass., 10 weekends to replace 14 bridges. WHY? I have written to the County Executive and will be reaching out to other county officials.
Why are Ardsley/Dobbs Ferry/Greenburgh motorists going to be inconvenienced for almost three years when major bridge reconstruction in other states and in other communities around the nation and world takes much less time?
I think that there should be an investigation of our bridge construction projects and compare what we do to other bridge projects. This is a video link of how China built a bridge -- work done in 43 hours, not three years!
Interstate-93 in Medford, Mass., was able to replace 14 bridges in Medford over the course of just 10 weekends between June and August 2011. Mass DOT used several innovations, a detailed traffic management plan and a comprehensive communications plan to complete the bridge work safely, efficiently, economically, and in a manner that caused the least possible construction-related impacts and congestion. The project was completed on-budget and ahead of schedule, replacing all 14 bridges in less than a year.
Using conventional methods this project would have taken at least four years and during those four years drivers would have had to endure long-term lane closures.
