I had no idea McCoys Creek was that far north! Anyone have a map showing the original route?
McCoy's Creek once had a rather vast salt marsh... The original road's that passed through went along the approximate route of Myrtle Ave
from The Brick Church southward, crossing McCoy's on a long fill and plank wooden bridge.
When the Jacksonville Terminal was built it required nearly 300 pilings driven about 75-100' deep for support. The yards themselves flooded terribly so after the 7-8 tropical storm in a row:
June 16, 1893 – Saint Marks is struck by a tropical storm. Moderate winds and rainfall occurs throughout the northeastern portion of the state, including a total of 1.51 inches in Jacksonville.
August 27, 1893 – The Sea Islands Hurricane parallels the eastern coastline as a major hurricane, producing winds in excess of 75 mph (120 km/h) near the coast. The winds destroy nine cottages in Mayport.
rallels the coastline about 60 miles (95 km) offshore. The storm tide was high enough that at low tide, it was at the position of the normal high tide mark. The tide caused street flooding in Saint Augustine, with heavy damage reported in Mayport.
September 29, 1896 – The fourth storm makes landfall as a major hurricane on Yankeetown with a pressure of 960 mbar. Strong winds downed hundreds of trees and caused severe damage amounting to $1.5 million (1896 USD, $36 million 2006 USD).[63] Multiple deaths were reported in the state.
October 2, 1898 – A Category 4 hurricane hits southern Georgia, causing severe damage in the extreme northeastern portion of the state. A storm surge of 12 feet floods and damages several buildings along the Fernandina waterfront. A conservative estimate for total damage in the state is $500,000 (1898 USD, $13 million 2008 USD).
August 13, 1899 – The San Ciriaco Hurricane parallels the eastern coastline, producing moderate winds and light damage.
October 5, 1899 – A tropical storm hits near Tampa and sinks a schooner off Fernandina Beach.
October 30, 1899 – A hurricane parallels the eastern Florida coastline, with several locations near the coast recording strong winds in association with the storm. No cases of serious damage are reported.
August 29, 1909 – A weak tropical storm crosses the eastern portion of the state, resulting in minor impact.
August 28, 1911 – A hurricane makes landfall on extreme southern South Carolina, with its large circulation producing moderate precipitation in northeastern Florida.
November 1, 1911 – Shortly after becoming an extratropical cyclone, a tropical storm hits near Cedar Key and causes unsettled conditions across the state for several days.
September 17, 1914 – The only tropical storm of the season strikes near the Georgia/Florida border, producing moderate rainfall and above normal tides.
August 1, 1915 – A minimal hurricane hits near Daytona Beach, dropping moderate precipitation and causing some damage.
May 14, 1916 – A minimal tropical storm crosses the state.
September 13, 1916 – A low pressure area moves ashore near Cape Canaveral, with the worst of its effects remaining offshore. Originally, it was classified as a tropical storm
September 30, 1919 – Moving ashore along the Georgia coastline, a tropical storm brushes northeastern Florida.
The tunnels 'beneath the station platforms' were actually built 1' foot above the high tide mark of McCoy's Creek, Tunnels, stairs, ramps and rooms were constructed at grade then the whole future rail yard was filled with 14' feet of dirt and compacted. The tunnels are strong enough to support the weight of the old Seaboard Air Line Railroad's articulated steam locomotives weighing in at nearly 1/2 million pounds each.
