I was out of my favorite tea and decided to walk to Harvest Market which requires crossing the Highway One / Noyo River Bridge. This bridge was recently rebuilt to the tune of around $30,000,000.00.
While walking the pedestrian walk way on the east side I noticed expansion joints in the guard rail separating us walker/bicyclers from the car/trucks. Expansion joints allow for the expansion and contraction of large object due to temperature changes. I discovered there were two of these joints located about equal distance from the north and south ends of the bridge.
After buying my tea I headed home and decided to stop and measure the “gaps”. Not having a tape measure with me I decided to use the change in my pocket.
As you can see, both gaps are just over .75 cents wide.
When I got home I checked the outside temperature. 47 degrees.
So, 47 degrees equals a little more than .75 cents.
As warmer weather arrives I will revisit the expansion joints and see how much they close as the bridge warms up.
And here I was thinking I was going to run out of things to do in this small town!!
