Federal, state and local officials held ground breaking ceremonies on Thursday, June 2 for the 156 million grade-separation project that will separate freight and passenger rail from auto traffic at the. The underpass opened on 22 May, 2019 and the entire project was completed in early July 2019, two months earlier than originally planned. California’s most dangerous railroad crossing in Santa Fe Springs should be perfectly safe once a railroad underpass is constructed. After the pouring of the concrete floor slab, the vertical AZ 25-800 piles were covered with an inclined concrete wall (1/15).ĭue to the tight planning and the limited space on the job site, all sheet piles, 390 tonnes in total, were delivered just-in-time by ArcelorMittal. The use of ArcelorMittal’s extra wide AZ-800 series allowed to minimize the total amount of welds to be done. After excavation to final level was finished, the interlocks of the AZ 18-800 piles were seal-welded to obtain a completely watertight wall. Measuring 137 ft long by 51 ft wide by 31 ft tall and weighing 4,450 tons, the first block. In parallel, the decks for track n☄, the service road and the bicycle track were constructed in situ. A 1 ft thick reinforced bottom slab called the jacking slab was constructed for the underpass boxes to slide across and a massive thrust block supported by engineered fill was constructed for the hydraulic jacks to push against, Carroll says. Once the sheet piles for the underpass entrance were installed, the excavation started underneath the prefabricated underpass decks. The vertical piles are connected by 4 prefabricated special transition piles to the inclined piles. As special features, the piles have an inclination of 11° (1/5) and follow a curve with radius of 400 m. The underpass entrances consist of 165 AZ ®18-800 sections in lengths between 5.6 m and 12.4 m. The underpass decks are supported by 46 vertical AZ ®25-800 sheet piles with lengths of 12.4 m to 12.6 m. To stay within this narrow time frame, a special solution was designed, using the top down method in combination with sheet piles. To reduce disruption, the construction of the underpass could interrupt the traffic on the train tracks only for one weekend on 5 and. This rare Warren deck truss carries a railroad track over an unpaved road and the west fork of Crooked Creek in eastern Franklin Township. The new underpass has two lanes for cars and trucks, and an elevated bicycle and foot path. The planned structure undercuts four railroad tracks, a service road and a bicycle path. To improve the safety of the busy railroad line Ghent - Antwerp that passes right through Lokeren, the existing railroad crossing is replaced with an underpass. Lokeren is a Flemish town of 41,000 inhabitants located between the cities of Ghent and Antwerp.
