At all times of the year, and especially during ski season, thousands of cars use SH-9 each day. Alternative routes for trucks, travelers, skiers, and hikers could result in hour-long detours. To avoid this disaster, they specified HDPE liners as this would provide a cost and time-effective option that would provide an increase in flow, fish baffles, inlet control devices, and custom length sticks to work within the right-of-way restrictions.
As well as, the culvert was compressed & losing its structural integrity, and a lot of aquatic life pass through the culvert.
Hundreds of cars were passing over the rusting culvert per hour, and the time to dig & replace would potentially interfere with ski traffic. As well as, the culvert was compressed & losing its structural integrity, and a lot of aquatic life pass through the culvert.
After looking at ovalled, large diameter HDPE pipe vs. Snap-Tite, all variables above were essentially equal. As a result, lead time was the deciding factor to avoid working into ski season. The slip-lining, bulkhead, and grouting were completed within a week to reinforce the structural integrity and allow enough time for the GC to pave the road before winter traffic ramped up.
