Amott Drainage Culvert Inspection and Rehabilitation

For the Port Jefferson Branch of the LIRR, McLaren is providing site/civil engineering services for the rehabilitation of the Amott Drainage Culvert between mileposts 30.3 and 30.6. The culvert's drainage deficiencies resulted in a washout that undermined the supporting structure of the north track and caused a train derailment. The culvert system consists of a street level drainage easement and overflow catch basins, a concrete spillway, collection box, two 36-inch diameter pipes approximately 36-feet long parallel to each other and perpendicular to the railroad tracks, a discharge headwall and spillway outflow area.
