Picayune Strand Restoration Project, US41 and CR92 Conveyance Features, Design-Build Contract

DESCRIPTION OF WORK: The principal intent of this project is to provide hydraulic connectivity through the addition of new culverts under or adjacent to existing US Route 41(US41) and existing County Road 92 (CR92/San Marco Dr.) in Collier County. At the end of the project all construction for maintenance of traffic must be removed and the original grades restored for all locations. Culverts under US41- Three (3) new single barrel 12 foot wide by 4 foot high concrete box culverts will be located under US41, approximately 1,000-feet southeast of the intersection of US41 and Tomato Road. The three (3) culvert locations will create new hydraulic openings for conveyance from the Tamiami Canal to the south side of US41. Culvert barrels will not require skews. The limits of construction including any approach construction are from Sta. 810+00 to 837+00. Maintenance of traffic may extend beyond these limits. Culverts shall be considered bridge-sized culverts and require load rating in accordance with Florida Department of Transportation (FDOT) requirements. Culverts parallel to US41- Three (3) existing 36” HDPE pipe culverts are located in the Tamiami Canal parallel to US 41. Culverts are on the north side of US 41 and approximately 400 feet southeast of the intersection of CR92 (San Marco Rd.) at US41. Existing culverts are located under a driveway, allowing ingress and egress to the adjacent residents at 20201 Tamiami Trail East, which is located within Collier-Seminole State Park. Existing culverts shall remain and an additional 36” culvert shall be added adjacent to the existing culverts. Appropriate safety features shall be provided where clear zone requirements cannot be met and may include but not be limited to new barriers and guardrail. Culvert shall be provided in accordance with FDOT Standard Specifications for Road and Bridge Construction Section 430 Pipe Culverts. Culvert under CR92 (San Marco Drive)- One (1) new double barrel 10 foot wide by 3 foot deep concrete box culvert will be located under County Road 92 (San Marco Drive), approximately 2,400-feet west of the intersection of CR92 at US41. The new culvert will create a hydraulic opening for conveyance between the north and south sides of CR92. Culvert barrels will not require skews. The limits of construction including any approach construction are from Sta. 558+00 to 578+00. Maintenance of traffic may extend beyond these limits. Culvert shall be considered a bridge-sized culvert and requires load rating in accordance with FDOT requirements. US 41 is an evacuation route. Vehicular, two-lane, two-way, and pedestrian access shall be maintained at all times during construction in the maintenance of traffic plan. CR92 is an evacuation route. Vehicular, one-lane, one-way, and pedestrian access shall be maintained at all times during construction in the maintenance of traffic plan.
