Renovation / Upgrading 1st Heinenoord Tunnel

Project Description

The 1st Heinenoord tunnel is part of the National Road Network and located in the A29 Motorway, close to Rotterdam. The tunnel was built in the late sixties and has a length of 1064 m; the closed section is approx. 614m long of which 571m is immersed (5 tunnel elements). The tunnel was originally accommodated with 2 road lane and a slow traffic lane. In the nineties a second (bored) tunnel was constructed which now carries the slow traffic. The old tunnel now accommodates 2×3 road lanes in two traffic tubes (but a central gallery is missing).

The old Heinenoord tunnel is currently being prepared for a substantial renovation and upgrading in order to meet current legislation. Next to upgrading systems and installations, a central gallery will be realized for escape and installations. It will be the first tunnel in a substantial renovation program of tunnels in the national road network in the province of South Holland. The renovation works for the 1st Heinenoord tunnel are scheduled for 2021-2023.
