The Myrtle Avenue Subway, opening up another convenient passage to the Riverside and Highway districts, has recently been accepted from the contractors by the city. This will give the company a new line to this territory, which we hope will be in operation within the present year.
Stone & Webster Public Service Journal, Vol. 4 page 419 January-June 1909
This streetcar line down Bay Street once used the Myrtle Avenue Subway to provide access to booming Westside streetcar suburbs like North Riverside, Murray Hill and Lackawanna.
Sec. 1722. Consideration.-It is a condition and consideration for the granting by the City of the privileges hereby granted that the Atlantic and East Coast Terminal Company, will, at its own expense, widen Forsyth Street between Cleveland and Jefferson Streets, making the south side of Forsyth Street a straight line from a point sixty (60) feet south of the north-west corner of Forsyth and Jefferson Streets, to a point sixty (60) feet south of the north-east corner of Cleveland and Forsyth streets, and will open and extend Forsyth Street, from Cleveland Street to Myrtle Avenue to a uniform width of sixty (60) feet, and will dedicate the land necessary for the widening and extension of Forsyth Street.
And as a further consideration said Atlantic and East Coast Terminal Company will, whenever required by City Ordinance, construct and maintain a subway under or a viaduct over its tracks on Bay Street to connect with any subway or viaduct crossing under or over the Jacksonville Terminal Company's tracks on Myrtle Avenue, such viaduct or subway to be constructed and maintained in compliance with the provisions of City Ordinance, and whenever the city shall have Forsyth Street paved between Jefferson Street and Myrtle Avenue, said company shall pay the proportion of the cost thereof charageable to its property, and also the part of such cost payable as the City's one-third of such cost; and as a further consideration said Atlantic and East Coast Terminal Company shall provide a foot bridge, or viaduct, along Davis Street above and over the tracks crossing said street as agreed upon by the Board of Public Works. (Id.2.)

The Myrtle Avenue Subway can be located in the center of this image, where the tracks in the railyard converge.
This image was taken on top of the Myrtle Avenue Subway.

The Myrtle Avenue Subway can be seen in the lower left section of this image.
The Myrtle Avenue Overpass carries I-95 over Myrtle Avenue and a railroad line in downtown Jacksonville. The main, steel arch span of the overpass is 386 feet long. There are 16 steel girder approach spans that bring the total length to over 1,400 feet in length. This bridge represents Florida's only steel arch, the state's only through arch carrying interstate traffic, and the only arch design serving as a grade separation. It was identified in an update to Florida's historic highway bridge inventory, and, as a result, the FDOT and the Florida SHPO concurred that this bridge represents a significant historic resource for the state.

The Myrtle Avenue Subway Today
The track and streetcars are long gone, but some of the supporting infrastructure remains.







The incorporation of the Myrtle Avenue Subway and tunnel lighting effects could make the proposed streetcar system an attraction itself.
The opening of streetcar service with this structure served as a critical connection between Downtown Jacksonville and the booming streetcar suburbs of Lackawanna, Murray Hill and North Riverside. The incorporation of this significant historical urban element into JTA's current streetcar plans could directly link a new line with the original one.

March 24, 2009, 08:08:01 AMVery similar in appearance and structure to the Krog Street tunnel between Cabbagetown and
Inman Park/Old Fourth Ward in Atlanta.
No graffiti though.

March 24, 2009, 10:20:55 AMInteresting. Growing up here in the 70s, I always heard it called the Myrtle Avenue Viaduct. Never knew it was part of a former subway. My father used to work at a company on Jefferson and when we'd pick him up from work, I'd beg my parents to drive through there. Often they'd humor me and put the car in neutral and rev the engine and honk the horn through there (if there wasn't too much traffic). At one point it was threatened to be closed permanently, and I am glad they've kept it open all these years.

March 24, 2009, 12:06:15 PMWhat?! No pictures of the hundreds of cars that have been submerged under there after heavy summer rains? That is its modern day claim to fame
P.S. As seen in one of your pictures, there was also an overhead track around the corner on Bay Street at one time. I also recall that Railway Express was where JTA HQ's is now currently. Any pictures of their operations?

March 25, 2009, 06:09:28 PMActually, according to my details I picked up from the Railroadiana show in February, where the JTA sits now used to be a roundhouse for the Atlantic Coast Line. Seaboard was out in Baldwin.

March 26, 2009, 11:39:26 PMY'all are BOTH RIGHT. The Roundhouse was back between the end of Bay and TTX. The LARGEST RAILWAY EXPRESS TERMINAL IN THE WORLD, was situated about where the center office building in the JTA complex is. This is not the office directly on Myrtle, but the one farther back. It was a HEAD Station with a Head House and all stub tracks backed in from the "S" line, they trailed off to the north toward Beaver Street.
I've got photos of both someplace, when I'm going through my stuff again, I'll scan and post a few. BTW the passenger station had 29 tracks and the Express Station had 32. The Terminal Company and Express Company wrote about a million letters back and forth with regards to the quicker breakdown of Express cars in and out of trains. I've got a handfull of those old letters. I also recall that Mercury Outboards was a MAJOR customer at REA. There was also a firm that shipped lots of florescent light bulbs in huge boxes with a sort of honey comb pattern.
The Jacksonville Terminal Company also switched the ATLANTIC AND EAST COAST TERMINAL COMPANY tracks up to the old Freight station North of Jacksonville Terminal. This is what the Bay street underpass was all about. The A&EC was all over a number of downtown streets in La Villa. The JTCO switchers were EMD products (GM) and were painted Orange with Green and Gold on them.

March 27, 2009, 07:13:15 AMI'm assuming the streetcars went through the middle arch of the subway. Any reason they put the big concrete barrier down the middle where the tracks used to be?

March 27, 2009, 09:02:33 AMThe A&EC terminal on the corner of Forysth & Jefferson in 1950. If we would not have been so tear down happy in the 1970s, this would have been a perfect facility for a farmer's market or marketplace.

March 27, 2009, 10:18:59 AMYou are correct. The streetcars went through the center of the subway. Keep in mind the streetcar is generally a much larger vehicle then the city bus, and it needs an overhead clearence of at least 16' min.. The clearence from the pavement to the top of the streetcar tunnel is only 10' feet today. This suggests that the car tracks were 6' feet below the pavement level. I have a book of engineering notes for the subway which has a short statement about depressing Bay and Myrtle at the intersection so the streetcar could line up with the short steep downgrade.
Also all you flooding tunnel buffs out there might want to consider that as the tracks were much deeper then the current pavement, guess where the original drains and pumps were? Had to be about 10' under the concrete barrier in the center.

April 18, 2009, 11:57:56 PMAfter the privilege of riding through the tunnel(if it could be called that) last year I wondered what the history of it was. I didn't think it was this neat
I just remember when we went through it, I was like "Woah this is awesome!". I know it might sound a little cheesy or something. But it was just something I never expected to be there.

March 20, 2010, 10:30:40 AMDespite the warning signs of low clearance, oversize vehicles still get stuck there. Yesterday (March 19, 2010) about 5 pm I was driving south on Myrtle and through the subway, when I saw a police car blocking the northbound side. Looking back, I saw a large aluminum box- either a truck or trailer- stuck rather far in. There was a large tow-truck waiting there for the duty ahead. Unfortunately, no camera with me to record same.
The concrete structure blocking the former streetcar lane is a box culvert.

March 20, 2010, 06:15:31 PMActually, the ACL facilities were out at Moncrief Yard, the Roundhouse and shop complex downtown was owned and operated by The Jacksonville Terminal Company.
JTCO also served as home to the Atlantic and East Coast Terminal Railroad which owned all of the tracks north of Bay and East of Myrtle-Davis-Cleveland Streets. A&EC wasn't a big railroad, it joined the JTCO at Myrtle Interlocking (under I-95 today) and ran north over Bay Street on a bridge. The abutment of the south side of that bridge are still visible from Bay Street. It ran east to west down the middle of several streets, into the edge of downtown. They also operated the huge blocks long Between the 60's and 80's, that sea of medium sized industry moved away from downtown, and finally with the redevelopment of the so-called "Prime Osbourne" the A&ECT was errased.
If you'd like to see what the unique A&ECT looked like, take a drive just off Myrtle, and head west on Dennis Street. After crossing the tracks on Dennis Street make a left on Watt's Street to either Harper or Swan, both of which are identical twins of the old A&ECT. If your tempted to try model railroading, I can't imagine a better prototype for a small space, switching layout then the A&ECT.
In the foreground are the tracks of the Jacksonville Terminal Company, just to the right of the new FREEway bridge one can spot Bay Street ducking under the A&ECT RY.
It's easy to spot the REA Terminal with it's 32 stub tracks (largest express station in the world) which sits square on top of JTA's facility of today. To the left of the REA Station is the JTCO roundhouse, shops, offices, and the railroads tank farm. The track between the REA station and the JTCO Roundhouse is the former "S" line, given to the city and abandoned. TTX sits where the JTCO facilities once stood. The ACL and the SOUTHERN ran up the West side of the JTCO facility, as today the NS and the CSX run on those same tracks today. The yard where JTCO allowed passenger cars to be stored, and cleaned was called Honeymoon Yard, perhaps for the sea of sleeping cars that once stood there.
Note the COAL TOWER on the point just below the REA STATION, the tracks from the roundhouse would have ran right under it on the way out. It's gone in the newer view (TOP PHOTO) and the lead track is bare.

March 21, 2010, 11:30:25 AMThe A&ECT was jointly owned by the ACL and FEC (thus the Atlantic & East Coast) and operated a large freight house that filled the area between Jefferson, Forsyth, Stuart and Bay streets. There was a large concrete ramp for automobile loading on the west end between Stuart and Lee. Stuart did not go through, but an elevated stairway allowed pedestrians to cross the tracks. The building was U-shaped, with a three story office building facing Jefferson, and a multi-bayed extension on each side of four tracks in the middle. The FEC's wing was on the south facing Bay; the ACL used the north side facing Forsyth. Arched doorways allowed truck access to the street side and railroad access to the tracks. The Gateway Model Railroad Club was housed in the two westernmost bays on the Forsyth wing for several years in the mid-Seventies, after moving from our original space in the old Pullman offices on the second floor of the Jacksonville Terminal building- on the north side, adjacent to Bay Street.
There was a fire in the office end of the freighthouse several years after we moved in. I was downtown and saw the smoke, and, with my heart in my throat, drove as close as I could to see if it involved our space. After the fire, the south wing was torn down, as was the office section, and the SCL closed off the east end with a blank wall. By then the building was being used mostly for storage and damaged freight. On Friday nights when we met to work on the layout, we would open both freight doors for ventilation in warm weather, and on a few occasions a switching locomotive would stop at our door. The crew would come in to look at our trains, and we would go out and look at theirs!
We learned that the building was to be razed, and the Club moved on to the West Bay Post Office Annex.
