Bridge to Nowhere Solution
How It Works
There are four distinct streams of data, encoded with five standard encoding schemes.
Each stream should be read as a long single series of data, which yields a phrase with a few extra letters.
Each phrase should hint the next in this order:
The board colors are resistor color codes, each board yielding one digit. * Reading the stream of digits by pairs, the numbers become ASCII, reading:
- YOU SAY YOU CAN’T SEE THE WAY? GEPH
* (including punctuation and spaces) 2. ‘Can’t see’ should be a decent hint towards Braille. * There are visible knots between some of the boards, on both ropes, so that a Braille letter may be read in the knots for three consecutive spacings. * For instance, a Braille S would look like this: 
* The phrase here is: * TELEGRAPH THE BLANKS AND YR 3. That phrase should hint the next step: the widths of the spaces between the boards may be read as Morse code. * Short gaps and long gaps (3" and 6") as the Morse, with really long gaps (12") separating one letter from the next. * The phrase thus read is: * HIKE ON WOODEN BITS OPH 4. And that should hint the final stream: the widths of the boards may be read as 5-bit binary. * That phrase is: * RESIST FEAR OBIA 5. Which then hints the first step: resistor colors.
Putting the extra letters together yields the answer.
