| A6. | The longest jacking drive in the US (one push), with the use of Meyer Polymer Concrete Jacking pipe, has been successfully done by Paul Vadnais Construction on the Murrietta project in Southern California. The initial plan was to split it into two sections (630 feet and 850 feet). The contractor decided to combine the drives to make it one push. The total drive was 1,480 feet. |
