The tunnel was built in the late sixties and has a length of 1064 m; the closed section is approx. 614 m long of which 571 m 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 Heinenoordtunnel 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 Heinenoordtunnel are scheduled for 2021-2023.
TEC is involved in this pilot renovation project as the Client Consultant and working in an integrated Project Organization with the Owner:
