On Tuesday, we posted our forty-ninth photo challenge to see how well you know Metro. I took five photos in the Metro system. Here are the answers. How well did you do?

This week, we got 30 guesses. Five of you got all five. Great work, Peter K, Craig, Alex B, FN, and Mr. Johnson!

Image 1: Wiehle Avenue

The first image shows the northern pedestrian bridge to Wiehle Avenue station. Almost all of you guessed one of the Silver Line stations, which is clear because of the architectural designs like the lines inset into the concrete and the latticework on the bridge.

But you can discount McLean and Spring Hill because the bridges at those stations are below platform level, not above. The bridges at Greensboro don’t have a kink or intermediate support columns, so you can also eliminate that one.

The bridge at Tysons Corner does have a kink in it, but the bridge is also built at an angle to the station, instead of being perpendicular like this one. And the kink is so close to the escalator shaft that you’d be able to see it (and the second bridge to Tysons Corner Center). This is the bridge over the Dulles Toll Road to the north side of Wiehle Avenue station. Ten of you got it right.

Image 2: Waterfront

The next image shows the escalator entrance to Waterfront station. To solve this clue, you needed to recognize the surroundings (or use Google Street View). The new building in the background was part of the Waterside Mall redevelopment, and its newness and design might have been a clue. There’s also a DDOT bike route sign at center. Twenty-two knew this one.

Image 3: Pentagon City

The third image shows the corridor leading from the faregates directly to the Fashion Center at Pentagon City. The high-ceilinged corridor here is fairly distinctive, and most of you figured it out. We had 25 correct guesses.

Image 4: Silver Spring

This picture shows the northern entrance to Silver Spring. Honestly, I was surprised about how many guesses on this one were of subway stations. The space here has columns and is quite large, both of which would suggest a mezzanine under an elevated platform.

Additional clues include the underside of the track/platform supports and the rooms on either side of the escalator. If you look closely, you can see that these walls don’t reach all the way to the underside of the platform. They’re independent of the structure. Thirteen guessed correctly.

Image 5: Court House

The final image shows one of the entrances to Court House station. This entrance is not maintained by WMATA, which is why the signage font isn’t Helvetica. Specifically, this is the entrance to Colonial Place, on the northwest corner of Wilson Boulevard and North Uhle Street.

The clues here were the non-standard font, the brickwork, and the building visible in the background. Nineteen of you correctly surmised that this was Court House.

Thanks to everyone for playing! Great work. Stay tuned. We’ll have five more images for you next week.
