Tunnel Repair Begins on CO I-70

Written by Randy Post

ENR reports that repair work has begun on a portion of the Hanging Lake Tunnel on I-70 in Glenwood Colorado after a crack opened up in the tunnel bore ceiling slab. Read on for more info. (CDOT Photo) The crack was first noticed during a routine inspection in July of 2006. In February of 2007, water began leaking from the crack. According to the Aspen Times News, the eastbound bore was closed to all traffic in late March. The fix will involve leaving the existing cracked slab in place, and drilling holes in it for additional reinforcement. A new slab will be poured above the cracked slab, and some sort of reinforcement will be added below the cracked slab to create a "sandwich" fix. I'm a little confused about the details, but in the ENR article it sounds like there will be excavation occurring above the cracked slab. At any rate, the construction is slated to last through October. technorati tags: tunnel bore Hanging Lake Tunnel I-70 Glenwood Colorado !
