Tunnels for the N44/A44 at Wassenaar will improve traffic flow

Traffic flow should improve between The Hague and Amsterdam in the Netherlands if tunnels are built at Wassenaar where the N44 becomes the A44 motorway. The number of vehicles that will travel through Wassenaar is expected to increase to 57,000 per day by 2030. However, only one if five vehicles are destined for Wassenaar, which has a population of around 26,000, according to a report by the Dutch civil engineering consultancy Royal HaskoningHDV,

Traffic flow should improve between The Hague and Amsterdam in the Netherlands if tunnels are built at Wassenaar where the N44 becomes the A44 motorway.


The number of vehicles that will travel through Wassenaar is expected to increase to 57,000 per day by 2030. However, only one if five vehicles are destined for Wassenaar, which has a population of around 26,000, according to a report by the Dutch civil engineering consultancy Royal HaskoningHDV,

The open tunnels would cost between €160-180 million as against around €700 million for a full tunnel for the N44/A44 underneath all of Wassenaar, a wealthy suburb of The Hague, which lies around 10km away.

    A variety of systems are available for quickly and efficiently removing water from roads as Patrick Smith reports The presence of water in a highway layer reduces the bearing capacity of the road, and in doing so it also reduces the structure's lifetime. Indeed, the recent extremely cold winter in many parts of Europe has shown that in colder climates there is a risk of frost damage when water is present resulting in costly potholes, so drainage systems performing properly are important in road design.

    Japanese consultants are planning to realign a Kenyan bypass, as Shem Oirere reports. Japanese consultants are resolving an engineering quagmire involving a 17.5km bypass in Kenya's Coast region. The new design realigning the bypass is underway by Japanese International Cooperation Agency (JICA) consultants. The road is an alternative link from the hinterland to the south coast and to the proposed Dongo Kundu Port. The 23m-wide bypass would also serve to reduce traffic congestion across the Likoni Channel.
