Airport
After landing [Runway] 19R; we were given taxi instructions by Ground to taxi M to the gate.  Half way down M; the taxiway had fresh paint and turned to join L. The center taxi line on M had been scrapped off and the line was now continuous with L (right turn). We discussed the fact that we would have to cross the double taxiway edge line to continue on M and decided that since that was our clearance and there were no obstacles in the way; we would continue on M to our gate.  At the gate; I checked the FAR/AIM as I had never crossed the continuous double edge lines before and was seeking clarification.I read that these lines mark the edge of the taxiway and separate the taxiway from an area aircraft are not supposed to be. I contacted Clearance/Ground and asked about our former taxi instructions and painted lines. He said we had complied with the instructions and was unaware of any taxiway realignment. A NOTAM did mention non-standard markings on M; but did not mention what they were. He contacted the airport facilities and they said they had painted the lines in anticipation of some work that they were doing. This led to confusion and the aircraft in an unanticipated position on a taxiway. The taxi clearance on the subsequent flight used M in the same way.
After clearing [Runway] 19R in MCI; Ground gave us 'taxi to the gate via M.' While going down M we noticed there were freshly painted markings. The markings were solid line taxiway edge markings; which we thought were strange as we would have to cross them to continue down M. We decided they were more than likely newly painted in conjunction with the construction going on near there; and since we were on the M Taxiway line and the sign designated we were on M; and there were no obstacles or other aircraft; we were safe to continue. Upon getting to the gate; the Captain talked with Ground and made sure we were correct with our analysis of the situation. Ground said they didn't know what the markings were as they were new and Airport Ops hadn't informed them of anything. They did find out that Airport Ops had painted them ahead of some construction as we had assumed. We re-read through the NOTAMs and saw there was one for non-standard markings on the taxiway; but didn't say specifically what they were. This is more of a heads up as it could potentially cause some confusion in a nighttime/raining/low visibility situation.
