details

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, CDOT 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.

problem

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.

solution

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.
