Two bridges over the Pirita River, Nehatu
Location: Nehatu village on the border with Tallinn, Estonia
About: The period of construction of the bridge is divided into four stages. This ensures uniform traffic, as well as the possibility of dismantling old bridges and building new ones.
A temporary bridge and an asphalted bypass road are built next to the existing two bridges in the lower reaches of the river.
Narva-Tallinn traffic is redirected to the temporary bridge and bypass road. Traffic in the Tallinn-Narva direction is redirected to the Nehatu 2 bridge currently ensuring traffic in the Narva-Tallinn direction. Thus, the Nehatu 1 bridge (currently providing traffic in the Tallinn-Narva direction) and its access ways will be freed of vehicles.
All traffic in the Tallinn-Narva and Narva-Tallinn directions occurring at stage 2 is redirected to the new wide Nehatu 1 bridge. Thus, the Nehatu 2 bridge and its access ways will be freed of vehicles. The temporary bridge will be dismantled. A new Nehatu 2 bridge and its access ways will be built.
Both bridges and their access ways are built and traffic is happening in both directions via 3 +3 lanes. In accordance with the permanent traffic scheme for Tallinn-Narva direction, the road shall be converted from four-lane into three-lane at 3 stage.
