The improvements entailed the replacement of existing guardrail systems and crash cushions, and construction of new concrete barrier walls along the H-1 Freeway between Middle Street (Mile Post 18.85) and the Punchbowl Street Off-ramp (Mile Post 22.48). The purpose of the project was to modernize roadside features to meet current Federal safety guidelines.
Civil Engineering scope included the preparation of plans to modify or upgrade existing guardrails, guardrail end treatments, concrete barrier walls, end post transitions, and impact attenuators and assist with post design services during construction. Associated work included street light relocation, roadside earthwork, pavement restoration, erosion control, traffic control plans, and preparation of a Transportation Management Plan.
WOC also assisted with the environmental permitting, a public informational meeting, and the preparation of a noise variance permit for night work.
