Sewer Mekelweg

On 29 March, work will start on the main sewer under the pedestrian and cycle path on Mekelweg

This work is required to repair leaks and prevent subsidence: in other words, in order to guarantee a future-proof sewer for the whole campus. The work is expected to last until the end of 2021. It will be completed in four phases.

Phasing schedule

Fase 1

  • 29th of March – early July
  • Stieltjesweg, junction between AS and CEG up to Berlagepad: end of March – early May
  • Berlageweg to Jaffalaan: early May – early July

Fase 2

  • May – August
  • Berlageweg to Broekweg (entrance to X).

Fase 3

  • End of June- early September
  • Van den Broekweg to Kruithuispad.

Fase 4

  • End of July – November
  • Heertjeslaan to Uytenbogaartsingel


Cyclists will be diverted via Schoemakerstraat and Leeghwaterstraat. See an overview of the diversions on the map below.

In line with the TU Delft Mobility Vision and the spatial development plans, initial efforts are now being made to encourage cyclists to use alternative routes. These routes are being used for the diversions. We are also looking from north to south at the places where cyclists and pedestrians meet. Suggestions for improving safety and traffic flow will be made for these junctions. This is all part of our efforts to achieve a future-proof campus: a park-like pedestrian zone where bicycles are ‘guests’.

Other work

Since the Mekelweg cycle path is being dug up in phases, we are seizing the opportunity to do other essential work, including replacing old cabling and piping (ICT), updating public lighting (LED), installing flexible ducting for glass-fibre routing (ICT) and other cables and pipelines.
