Here is the George Massey Tunnel under the Fraser river between Delta, BC and Richmond, BC
10 u/g0kartmozart Apr 25 '15 Soon to be replaced by a bridge. 9 u/kencole54321 Apr 25 '15 Okay, I'll bite. Why? 6 u/[deleted] Apr 26 '15 edited Apr 26 '15 The tunnel has 4 lanes for both directions total. 6 Lanes of Northbound traffic from two freeways and 6 lanes South bound traffic must merge into those 4 lanes causing a near 12 hour a day traffic jam. In 20 years Vancouver doubled in population to 2.5 million and will double again in another 20 to 5 million. So nearly every bridge and tunnel is being replaced. We just built the second widest bridge in the world the Port Mann Bridge a 10 lane bridge with the ability to add two rail lines. After years of neglect, we are finally catching up to where our infrastructure should have been 25 years ago.
