Narrative:

While taxiing to runway 27L from center remote, we were given instructions to taxi via 'taxiway north, taxiway Y, taxiway Y1, taxiway 2, runway 8, runway 27L.' we missed taxiway Y1 and arrived at taxiway hh before stopping and questioning ground. They attempted a rerte on another taxiway, but we were eventually told to make a 180 degree turn onto taxiway Y1, as previously instructed. On arriving at taxiway Y1, we clearly saw the sign heading northbound on taxiway Y (abeam fire house), but noticed that no sign for taxiway Y1 sbound on taxiway Y exists. Subsequent taxied through the same area during the week confirmed suspicions. Sign missing could be due to local construction. As a result of this situation, all first officer's have been briefed to maintain airport diagram out even at our hub, in addition to questioning my every turn if in doubt. No conflicts with traffic existed. Controller was very helpful. Callback conversation with reporter revealed the following information: analyst called facility specialist. Facility specialist advised that the FAA, airport officials and users started a 'runway incursion action team' to address taxiway and runway problems/concerns due to planned airport construction over the next 3 yrs. Txwys Y and Y1 signage have already been addressed. Also, txwys Y and V adjoining runway 27L. The airport is also under constructing a new runway, 800 ft north of runway 27R.
