What is the narrowest gap separating each of the following Straights?

Incidentally, with regards to the English Channel, the Eurostar train goes from London’s Waterloo to Paris’ Gare du Nord station in 3 hours and 10 minutes traveling at speeds up to 160 kph/100 mph. Also, every day there are nearly 300 attempts made by illegal aliens to cross into the UK via sneaking through the tunnel. The record for swimming the English Channel currently held by Chad Hundeby of the USA with a time of 7 hours, 17 minutes back in 1994.
