when did the panama canal started being built
History of the Panama Canal Construction of the canal began on January 1, 1881, with digging at Culebra beginning on January 22.[1] A large labor force was assembled, numbering about 40,000 in 1888 (nine-tenths of whom were afro-Caribbean workers from the West Indies). Although the project attracted good, well-paid French engineers, retaining them was difficult due to disease. The death toll from 1881 to 1889 was estimated at over 22,000, of whom as many as 5,000 were French citizens.[3]
New Madrid Seismic Zone Instruments were installed in and around the area in 1974 to closely monitor seismic activity. Since then, more than 4,000 earthquakes have been recorded, most of which were too small to be felt. On average, one earthquake per year is large enough to be felt in the area.
Red Fort It was designated a UNESCO World Heritage Site in 2007 as part of the Red Fort Complex.[2][6]
San Francisco–Oakland Bay Bridge Tolls were subsequently raised to finance improvements to the bridge approaches, required to connect with new freeways, and to subsidize public transit in order to reduce the traffic over the bridge.
