I can certainly understand the County's reasoning. The old bridge was probably a maintenance nightmare. From a transportation efficiency and legal liability standpoint, necking the two-lane road down to a single lane didn't make much sense. But I have to say I'm mourning the passing of this relic of simpler times.
Based on the stories that friends have told me about the roads between Auburn and Lincoln, Mt. Vernon and Wise Roads were not paved until the second half of the 20th Century (perhaps Jean Allender or Betty Samson can fill in the details). The Doty Ravine Bridge was a reminder to me of these simpler times - like the bridge, the roads were single lane as well.
More importantly, the one-lane Doty Ravine Bridge was a reminder (in an increasingly fast-paced world) to slow down. If someone was approaching the bridge from the other direction at the same time, both of us would decelerate (usually). We'd make sure that whoever was closest to the crossing made it over first.
This slowing down also required neighborliness. Most of the folks I passed crossing the Doty Ravine Bridge were strangers, and yet we nearly always waved at one another as we crossed. The one-lane bridge was a reminder, in some ways, that our destination wasn't more important than safety and politeness. In an increasingly busy (and rude) world, I'll miss this reminder.
I suppose I'm sounding like a curmudgeon. Progress is positive, right?! I expect that the county road department was tired of dealing with damage to the bridge caused by people who didn't slow down and wave. I expect the county counsel was tired of the liability faced by the county when people caused accidents. But with a two-lane bridge, I'll make it to Lincoln 10 to 15 seconds faster than I would have otherwise. I'd gladly give back that time. I'll miss this reminder of our rural roots.
