Thankfully, refineries can customize the product a bit for the market. They do this mostly to change the boiling point, but it affects freezing point too. Northern regions in winter will have gasoline with a lower freezing point. Southern Arizona in summer will have gasoline with a higher freezing point. Gas with ethanol will freeze lower. I would hazard a guess that for northern-state winter blend gas, going down to -70F (the freezing temperature of octane) is fine. Of course, that's probably all moot. Gasoline engines don't start when they get too cold, because the fuel doesn't vaporize properly.
Visitors Guide. Lake Pontchartrain Causeway. The Lake Pontchartrain Causeway holds the title for the longest bridge over water at 23 miles long. It officially opened in 1956, and cut travel time from North Shore communities to the city of New Orleans by 50 minutes.
That bridge was replaced with a concrete bascule bridge in 1968. The bridge became a very popular fishing spot for local residents, and was nicknamed The fishingest bridge in the world. The current bascule bridge opened on November 18, 2012.The current span is 9 feet tall, similar to its predecessor.After its demolition, the previous bridge (the one built in 1968) will be made into an artificial reef at Novak's reef, which is about 3 miles off the coast of Charlotte County.he current span is 9 feet tall, similar to its predecessor.
