Tunnels are being proposed to improve traffic flow between The Hague and Amsterdam in the Netherlands. The Dutch civil engineering consultancy Royal HaskoningHDV has carried out a study into traffic flows between the two cities. According to the study, traffic flow will improve if tunnels are built at Wassenaar where the N44 road becomes the A44 highway. The study predicts and increase in traffic volumes to 57,000 vehicles/day by 2030.

The final span of the Governor Mario M Cuomo Bridge, which replaced the Tappan Zee Bridge, has now been opened to drivers. The opening was delayed slightly due to concerns over the state of a section of the old bridge, now being demolished. The new link was constructed by a joint venture headed by Fluor. With the new bridge opening, all four lanes of eastbound traffic shifted to the new second span. T
