Steel Girders Go Up The Port Access Road Project
initiated a new work element in May with the placement of steel girders over I-26 to support a new ramp from I-26 Eastbound onto Meeting Street. Each girder is 5 feet tall, approximately 100 feet long, and weighs between 14 tons and 18 tons. Before being trucked to the construction zone, all of the steel girders are fabricated, tested and painted in Augusta, Georgia. The month began with the installation of four girders on the north side of I-26 the night of May 1st. Once these girders were in place, crews turned their focus on placing girders over I-26 Eastbound and Westbound lanes. It took six nights to complete this crossing, including time to mobilize equipment, place four lines of girders with two girders in each line, and bolt support diaphragms between the lines of girders. Check out the SC Port Access Road Facebook Page for time-lapse videos showing how some of the girders were placed on the north side of I-26 and over the Interstate. Additional night time, dual lane closures in both the east and westbound lanes will be necessary to install traffic protection and Stay-In-Place (SIP) deck forms. Plywood and 4”x4” wood framework will be added between the girders to protect traffic from any loose materials or tools that are accidentally dropped. SIP deck forms are steel pans designed to fit between the steel and concrete girders. These forms minimize bridge deck construction time and costs because they allow work to be done from above and do not have to be removed after the concrete deck is formed. Building the Port Access Road Interchange ramps to and from I-26 eastbound will require two more girder crossings over I-26 currently scheduled for 2019.
South-end of Meeting Street Road Scheduled to Close June 21, 2018 Construction of the new Stromboli Avenue and Carner Avenue/ (US 52) intersection requires Meeting Street Road, south of Barnaby Lane, to be closed with a new cul-de-sac. This permanent closure has been scheduled to take place on June 21, 2018. Meeting Street Road users can continue to choose other routes such as Clement Avenue to connect with Carner Avenue.
