TL;DR

The challenge asks for the street where a bridge in a YouTube video is located. After analyzing the bridge image, I identified the Little Nestucca River Bridge and confirmed it using coordinates and additional cross-referencing. The correct street is Little Nestucca River Road.

Solution

Step 1: Analyzing the Image

The first step was to use Google Reverse Image Search on the provided photo of the bridge.

The first result was interesting, so I clicked on it: https://weareplaygrounds.nl/lorn-timesink-directed-by-pavel-brenner/

After scrolling down, I found a high-quality version of the bridge image.

In this version of the image, I zoomed in on a sign and could read "Nestucca River." This gave me a key clue for the next step.

Step 2: Identifying the Bridge

My search results led me to a website that described the Little Nestucca River Bridge I, which seemed to match the bridge in the photo.

I found the coordinates for the bridge: 45° 6' 29.98" N, 123° 49' 26" W and plugged these into Google Maps to check if the location was accurate.

Step 3: Verifying the Location

To verify that this was the correct bridge, I cross-referenced the video still with images and information from the BTS of the Timesink music video on Instagram:

This gave me additional visual confirmation that the bridge was indeed the correct one.

Step 4: Confirming the Street Name

I searched for information on the bridge's street and found that there is a Little Nestucca River Road with a truss bridge, which matched the bridge I was analyzing.

I also searched for where Timesink by Lorn was filmed on Google, and this gave me further confirmation that I was on the right track.

It was accepted!

Notes

• Reverse Image Search: Helped find a high-quality version of the bridge image, essential for identification.

• Cross-Referencing: The Behind-the-Scenes (BTS) footage from Timesink was invaluable for confirming the bridge location.

• Structurae Database: A top resource for structural engineering, with over 85,000 structures and 600,000 publications, it helped verify the bridge details.
