Sue, attached you will find the construction drawings for the stream crossing at Smith Crossing for your use.
These drawings reflect the construction sequence to install the pipe in the dry as well as the detail of the outlet stabilization for the
pipe.
Hopefully these plans clarify some of the questions that you may have had. Please feel free to contact our office if you need any
additional information or if you have any questions.
Thank You,
