SR 105 is the only access road to Jacksonville Zoo and Gardens. In fact, the entire road was named Heckscher Drive for years. However, the section from I-95 east to I-295 East Beltway was renamed Zoo Parkway.
Route description
SR 105 begins at an interchange with I-95. SR 105 has an interhcnage with U.S. Route 17 less than a mile from its western terminus. From there, SR 105 can be characterized as a 4-lane mid-speed highway that parallels the north bank of the St. Johns River through a rural area. After 5.9 miles, traffic slows down briefly to a pair of traffic lights. In between the traffic lights, there are on-ramps for access to I-295. After the traffic lights, SR 105 begins to pass through marshland along the St. Johns River. The speed limit for this portion of the road is 45 mph. During this stretch, SR 105 intersects all the roads that cross the St. Johns River. After intersecting Dave Rawls Blvd, the SR thins down to a two lane highway. The road procceeds to travel through mostly marshland, crossing over Little Clapboard Creek and Sisters Creek. After 9.3 miles of travelling through marshland, SR 105 intersects with State Road A1A, which crosses the St. Johns River by ferry service. At this point, signage disappears for SR 105 as it converges with SR A1A. SR 105 follows SR A1A over Fort George Inlet and through Little Talbot Island State Park and Big Talbot Island State Park. SR 105 then crosses the mouth of the Nassau River into Amelia City. SR 105 follows the beach due north until its reaches its western terminus in Fernandina Beach.
History
SR 105 travels concurrent with SR A1A from the Mayport Ferry up to Fernandina Beach, however, over the years, signage has been removed.
