In Our View: Light rail on new I-5 Bridge: To be or not to be? The Columbian Share: Most of us learned an important life lesson years ago: When facing difficult tasks, do the hardest part first. As Mark Twain quipped: “Eat a live frog first thing in the morning and nothing worse will happen to you the rest of the day.” While we would not recommend eating a live frog at any time of day, the point is well taken. Get the hard part out of the way, and the rest is relatively easy. Which ties into discussions about a replacement for the Interstate 5 Bridge and the inevitable debate over light rail. The possible extension of Portland’s MAX system to Vancouver is likely to be the definitive issue for any eventual proposal; as such, it can be ignored for only so long as a bistate bridge replacement committee delves into its work.
