The Combined Sewage Storage Tunnel (CSST) is closer to becoming a reality in the capital as the tunnel-boring machine emerged from the rocky cliff behind the Supreme Court of Canada on Thursday afternoon.

Tunneling started on Chamberlain Avenue in December 2017, travelling 2km to the Ottawa River from eight-storeys below Kent Street.

The CSST will help cut down on the number of sewage overflows getting into the river after a major rainfall.
