ISLAMABAD - Briefing the media persons over the traffic diversion plan for the construction of Zero Point Interchange, Chairman of Capital Development Authority (CDA) Kamran Lashari announced here on Friday that work on the mega project would commence on July 15. Lashari informed that the grade separation project at the gateway to the federal capital would cost Rs 2.27 billion and would be completed in two years. He maintained that the motivated diversions were aimed at avoiding hassle during execution of the project and hoped that the commuters would experience no major annoyance. The SSP (Traffic) Muhammad Zubair Hashmi, CDA Member (Engineering), Moeen-ud-Din Kakakhel, Traffic Engineer CDA, Azam Lodhi, Project Director Zero Point Interchange, Mumtaz Hussain and other senior officials of the Authority were also present in the briefing. Hashmi informed that the ITP and CDA had chalked out a comprehensive plan for the traffic diversion during the construction of the interchange. As per the plan, traffic from Rawalpindi and Islamabad Highway to the capital city would be diverted on Garden Avenue from sectors I-8, H-8 signal while 9th Avenue would cater the traffic entering the Capital from the IJ Principal Road. The interchange experienced severe traffic congestion at the peak hours for the last many years as an estimated number of 1,15,000 vehicles made way to and out of the capital through it. It is why people, not only in the twin cities but around the country, who frequently visited the capital, were impatiently awaiting some sort of solution at the place. However, despite announcing one and the other date for commencing the work on the project, the same remained in doldrums for more than a decade. Last year, when CDA was all set to kick off the project, incident of the Sher Shah Northern Bypass Bridge in Karachi compelled the city managers to think again over the project design. Actually, both Zero Point Interchange and Sher Shah Bypass, which had collapsed only a week after its formal inauguration, killing six people, was designed by the same consultancy firm, M/S ECIL. However, the Authority got the design revised by renowned consultant Col (r) Muhammad Iqbal Haq, who  okayed the design as safe. While revealing details of the project, Project Director Mumtaz Hussain informed that the interchange had a Clover Leaf type design with three loops (an inclined surface or roadway that takes traffic from one level to another), four slip roads, pre-stressed RCC girder bridges, underpasses, reinforced earth walls and four pedestrians bridges. The interchange, which would serve as a junction for the five lanes Kashmir Highway and six lanes Islamabad Highway, was designed to cater the traffic needs till 2030, Hussain maintained, adding that the tendering process of the project would be completed by June 20. He further informed that construction work of the project would be executed in three phases. In first phase, loops and slip roads of the interchange would be constructed while the existing roads would remain in use, he said. In second phase, two bridges, one each on Islamabad Highway and Kashmir Highway, would be constructed. During the construction of these bridges, traffic would be diverted to loops and slip roads of the interchange and one side of both the highways would be closed for traffic, he informed, adding that the remaining work would be executed in the third phase.
