Los Angeles’ East Central Interceptor Sewer (ECIS) reached a milestone at the end of September, when the fourth and final TBM broke through, completing a 5.2km drive.
A total of 18.3km has been excavated by the Kenny/Shea/Traylor/Frontier-Kemper JV, using four Lovat EPB TBMs, for the Los Angeles’ department of public works.
