The Main Street Bridge was the second road bridge built across the St. Johns River in Jacksonville, Florida (the first was the Acosta Bridge). It carries four lanes of traffic, signed as US 1/US 90 (SR 5/SR 10). The lift bridge opened in July 1941 at a cost of $1.5 million. In 1957 it was named after Mayor John T. Alsop, Jr., but continues to be known, even on road signs, as the Main Street Bridge.

North (downtown) approach

When the bridge was first built , its north end was at the intersection of Main Street and Water Street. Traffic continued north on Main Street, with a one-way pair being made at some point; after that, northbound traffic turned right on Water Street and left on Ocean Street. A one-way pair is a pair of parallel, usually one-way streets that carry opposite directions of a signed route or major traffic flow. ...

In 1978, several approach bridges and ramps were built. Main Street now goes over Water Street, and a ramp now carries all traffic from the bridge diagonally into Ocean Street, with a second bridge over Water Street. Ramps provide access to and from Water Street. 1978 was a common year starting on Sunday (the link is to a full 1978 calendar). ...

South approach

The bridge originally ended at Miami Road (now Prudential Drive). When Jacksonville's original expressway system was built, in 1958, ramps were built connecting this intersection to the new expressway (now I-95 (SR 9)) connecting the Fuller Warren Bridge and the Acosta Bridge to Phillips Highway (US 1 (SR 5)) and Atlantic Boulevard (US 90 (SR 10)). An expressway is a divided highway, usually 4 lanes or wider in size, where direct access to adjacent properties has been eliminated. ... 1958 was a common year starting on Wednesday of the Gregorian calendar. ...

In 1968, a flyover was built between the ramps to I-95 (SR 9) and the bridge, with frontage roads continuing to serve Miami Road and several other cross streets. Thus there is now uninterrupted traffic flow from I-95 (SR 9) to the Main Street Bridge. 1968 was a leap year starting on Monday (the link is to a full 1968 calendar). ...
