Actually, local residents know there is a way to avoid the traffic lights and congestion on Highway 95 in much of Lake Havasu City.
The trick is to leave 95 and take nearby London Bridge Road, which parallels 95 along the lake from just north of London Bridge until it connects with 95 again north of Walmart. IIRC, London Bridge Road has few or no traffic lights, light traffic, and just a few stop signs. It saves a lot of time taking this route through LH City.
