2000 – Trunk Sewer Crossing I-5

Feasibility study for micro-tunneling new 84" Combined Sewer Pipeline crossing under I-5 “boat” section

MRPE surveyed Freeway and adjacent properties at crossing, mapped topography and drafted plan & profile drawings

Freeway access required an encroachment permit and specialized safety training. A variety of improvements impacted alignment thru the Freeway and on either side including thickened concrete designed to prevent flotation of freeway during shallow groundwater.
