Interstate 10 East at Exit 556A: TX Loop 1604 - Anderson Loop. Although 'Anderson Loop' is omitted from the exit sign itself, it is fairly common around the San Antonio area to see advance signs for upcoming exits which include the road's locally known name. You will see another example of this ahead with Interstate 410 (Connally Loop).  (Photo taken 5/21/15).

Interstate 10 East at Exit 566C: Hildebrand Ave / Fulton Ave  (Photo taken 5/21/15).

Ahead, Interstate 10 undergoes a brief upper and lower level split. Essentially, this means that I-10 is double decked for a brief distance ahead. This upper/lower level configuration was built as the "Downtown Y Project", which was completed in 1991. Since the I-10 and I-35 mainlines through the downtown San Antonio area were built in narrow canyons, this limited them to 2 lanes in each direction. As San Antonio grew rapidly, this soon became inadequate for carrying traffic through downtown. The best solution was to add elevated structures which overhang the the lower level and adjacent side streets, making the "widening" of I-10 possible through this double decking with the upper level carrying 3 lanes of traffic in addition to the original 2 lanes. The main benefit of this upper/lower level configuration is that it allows through traffic to separate itself from local traffic, and when the two decks (levels) re-merge about a mile or so later, through traffic can already be in the proper lane(s) to merge onto Interstate 35 North, which is the example in this picture. This made for much improved traffic flow through downtown.  (Photo taken 5/21/15).

As we near downtown San Antonio, the speed limit decreases to 60 mph.  (Photo taken 5/21/15).

Interstate 10 East at Exit 567: TX Loop 345 - Fredericksburg Rd / Woodlawn Ave. The signs to the left of this exit sign show which level (deck) you should take to access the exits listed on each sign. Take the lower level (to the left) to access Colorado St and Frio St. Stay on the upper level to access Culebra Ave and Santa Rosa St.  (Photo taken 5/21/15).

Interstate 10 East at the upper/lower level split just past Exit 567. Through traffic headed for Interstate 35 North toward Austin is advised to take the lower level here, to the left. I-10 through traffic and traffic headed to Interstate 35 South toward Laredo is advised to remain on the upper level of I-10 (right 3 lanes). Since I was headed through San Antonio on I-10 East, I remained on the upper level, which is what the next few pictures will be from.  (Photo taken 5/21/15).

Interstate 10 East at Exit 568: TX Spur 421 - Culebra Ave / Bandera  (Photo taken 5/21/15).

Interstate 10 East approaching Exit 570, the junction of Interstate 35 in downtown San Antonio - 1 mile.  (Photo taken 5/21/15).

Take Exit 569C to UTSA Downtown Campus and Our Lady of the Lake University.  (Photo taken 5/21/15).

Interstate 10 East at Exit 569C: Santa Rosa St / Downtown  (Photo taken 5/21/15).

Interstate 10 East / Interstate 35 South duplex in downtown San Antonio undergoes an upper/lower level configuration of its own ahead. Interstate 35 South through traffic is advised to use the lower level ahead. Through traffic for Interstate 10 East and US 87 South is advised to remain on the upper level. Oh, and use Exit 155B to The Alamo.  (Photo taken 5/21/15).

Interstate 10 East / Interstate 35 South at Exit 155B: Frio St / Cesar E Chavez / Downtown  (Photo taken 5/21/15).

Interstate 10 East / Interstate 35 South approaching the upper/lower level split. This one provides two lanes for each deck. Again, through traffic for Interstate 35 South toward Laredo is advised to use the lower deck ahead, since when it re-merges with the upper deck, it will put you in the proper lanes to stay straight onto I-35 South, avoiding any need for sudden lane changing. Interstate 10 East through traffic should stay to the right to take the upper level.  (Photo taken 5/21/15).

Use the upper level of Interstate 10 East / Interstate 35 South to access the exits to S. Laredo St, Cevallos St, and Nogalitos St.  (Photo taken 5/21/15).

Interstate 10 East / Interstate 35 South at Exit 155A: TX 536 Spur - S. Alamo St. Just past this exit, you see the upper/lower level split begin to take place.  (Photo taken 5/21/15).

Now on the upper level of the Interstate 10 East / Interstate 35 South upper/lower level configuration, two lanes are carried on each of the decks (levels) as you see here. Take Exit 154B to the Produce Terminal.  (Photo taken 5/21/15).

Interstate 10 East / Interstate 35 South at Exit 154B: S Laredo St / Cevallos St  (Photo taken 5/21/15).

Here we see the two lanes of the lower level of the Interstate 10 East / Interstate 35 South double deck configuration merge back with the upper level's two lanes. You can see why through traffic headed for Interstate 35 South toward Laredo was advised to take the lower level, since it places you in the proper two left lanes to continue on I-35 South once the re-merging with the upper level takes place here. Exit 153, for Interstate 10 East/ US 90 East / US 87 South toward Houston and US 90 West toward Del Rio is 3/4 mile ahead, on the right.  (Photo taken 5/21/15).

Interstate 10 East / Interstate 35 South at Exit 154A: TX Spur 353 South - Nogalitos St  (Photo taken 5/21/15).

Use Exit 153 to US 90 West to Hondo and Uvalde.  (Photo taken 5/21/15).

Also use Exit 153 to US 90 West for Port San Antonio and Lackland Air Force Base. Stay to the right off Exit 153 to access US 90 West, as you will see in the next two pictures.  (Photo taken 5/21/15).

Interstate 10 East / Interstate 35 South at Exit 153: Interstate 10 East / US 90 East / US 87 South - Houston; US 90 West - Del Rio  (Photo taken 5/21/15).

On the ramp for Exit 153, keep to the left to remain on Interstate 10 East / US 90 East / US 87 South toward Houston. Stay to the right to go onto US 90 West toward Del Rio.  (Photo taken 5/21/15).

Now that Interstate 10 East has freed itself from its concurrency with Interstate 35, the speed limit increases to 65 mph.  (Photo taken 5/21/15).

Take Exit 581 1/2 mile ahead to Interstate 410, Connally Loop. Once again we see an example of how advance mileage signs in the San Antonio area will include the locally known name of the road on them, in this case, Connally Loop, but omit them from the exit signs themselves.  (Photo taken 5/21/15).

Take Exit 581 to Ackerman Rd and Kirby.  (Photo taken 5/21/15).
