The SNMO/HTTP EXTERNAL ADAPTOR description is incorrect and should be SNMP/HTTP EXTERNAL ADAPTOR. Due to the lateness of this discovery, no addendum can be issued, but the item description will be changed in BidX. Bidders will need to download a new BidX file on Monday(today) after noon. The Special Provision for UNINTERRUPTIBLE POWER SUPPLY in the proposal will apply for this item.

Please review the mast arm length needed for Pole C. The legend calls for a 55' mast arm. However when you scale the mast arm in the plan view, it is under 49'. This would allow for a Type A shaft to work for Pole C. We would request that these items be addressed in an Addendum instead of a work order after award.

The correct mast arm length is 55’. This length allows the signal head to line up with the turn lane plus a minimum 1’ extension of the mast arm beyond the last signal head.
