Keith,
Please see below for the responses to the signal questions. They’ll call you shortly.
Also, I can’t make the meeting today but I would like to come out sometime in the next few weeks to observe the
construction progress and take pictures.
Dan,
To clarify Robert’s questions: Go by the foundations named in the table, 30-A for the 32’ mast-arm. As stated by
the project engineer, the poles are TxDOT with a modified hand hole to accommodate the decorative base. The
poles are MOD A, Type II mast arms since we have two signal heads per pole. Due to the length of the poles, the
deletion of the tenon will not have a drastic effect on the head placement per approach due to adequate mast arm
length. As stated by Note 7 on TS-2, please provide dampers for each of the mast-arms.
Thanks,
Dan Prendergast, E.I.T.
