RE: Permanent Traffic Signals at Parkway Boulevard/Denton Tap Road
and Bethel School/Denton Tap Road; Modification to Traffic
Signal at Moore Road/Sandy Lake Road

Dear John:
The Director requested that I review the plans for Bethel
School/Parkway and Denton Tap traffic signals. I request that
the Multisonic 820 A Controller be specified for each project.
I would like to keep all equipment in the City in uniformity. This
would include the Moore and Sandy Lake Road upgrade project, if
applicable. Also at this site the box span would be preferred,
due to the weight of the signals and the continuous sagging. An
additional lift span has already been installed at this location
due to the sagging.
In appendix A - 2.0 Scope of Work, Alternate No. 2, there is only
one traffic loop existing; the southbound through and turn on the
north side of the intersection.
I would like to have copies of the manufacturer's instructions,
etc. covering section 01750 Warranties B & C.
On the preliminary plans, I would like to see advance loops installed
on Denton Tap Road at both locations and consideration for advance
loops off West Parkway Boulevard.
Is the third signal head for east and westbound Bethel School Road
traffic mounted on the upright mast arm needed?

I do not like the set up of the third signal head attached to the
pedestrian walks. The signals within the city should be uniform.
If you have any questions, please contact me at 462-8495.
