On July 24th , 2019 the official inauguration ceremony of the RijnlandRoute TBM took place (click here for a video). In early August the 100 m long TBM, built by Herrenknecht and named Gaia, after the Greek goddess of the earth, will start boring the 2.5 km tunnel. In 6 months time the TBM will reach its destination at the Stevenshof district in Leiden. Then in 2020, the TBM will cover the same distance again for the second tunnel. RijnlandRoute is a new road connection from Katwijk, via the A44, to the A4 at Leiden. The road solves current bottlenecks and guarantees traffic flow in the Holland Rijnland region, in particular around Leiden and Katwijk.
