It has a river clearance of 25m to the soffit of the deck and carries four lanes of traffic. The cable-stayed section consists of two spans with a single tower; the main span is 185m long and the back span has a length of 142.5m. A solid counterbalance abutment on the back span end was built to compensate the corresponding scope of works performed imbalance in dead load. A 45m-long approach span connects the cable-stayed part to the west abutment. The cable-stayed deck is supported by a single pylon via a central plane of 14 cables on each side of the tower. At deck level, the cables are anchored at 7m centers into a central beam that transfers the horizontal component of the stay’s force into the concrete deck through shear studs. The deck is 25m wide and is designed to carry two traffic lanes in each direction, separated by a 4.4mwide central reservation. Twenty-eight stay cables with individually galvanised, waxed and sheathed strands varying in size from 6-43 to 6-85 and in length from 40m to 126m. Forming the stay-cable bundle involved installing each individual strand one at a time and encapsulating them using an external HDPE pipe with double helical ribs.
