Narrative: It was a normal flight with delays and thunderstorms going into DTW. During descent; vectors onto final we received an intermittent caution of Integrated Drive Generator (IDG) 1. I started the APU in anticipation of single generator operations and checked the status of the generator via the electrical page and the overhead panel. The left IDG on the electrical page would flash yellow and green with a caution associated. We decided it would be best to resolve the issue on the ground. During the approach and landing the IDG 1 caution message continued to go off. On rollout we taxied the aircraft towards the first available high speed exit A4 which was NOTAMed closed at the time of arrival. ATC told us after we were heading towards A4 to turn off on A5. I said 'We are turning off A4.' ATC replied 'Do you see the barricades?' I replied 'Yes sir; we do. We can turn around and taxi to A5.' Tower at this time called the proceeding traffic to go around. ATC then said 'Aircraft X; re-enter RWY 4L and taxi via A5 Alpha; and await further instructions.' We taxied on the runway and off A5 and on Alpha. Tower then transferred us to ground and we continued our taxi to the gate with IDG 1 caution still periodically chiming. We shut down engine 1 and proceeded to gate with no further issues. There was no contact with any barriers nor was there any damage of any sort to the aircraft or airport property. The cause of the event was inadequate briefing on current NOTAMs to highlight runway taxiway closures. This was due to delays and thunderstorm avoidance which diverted attention from a more complete brief. During final descent we had an IDG 1 caution chime and we decided to resolve the issue after we had landed. During approach and landing the chime did cause a distraction. This distraction diverted our attention and caused us not to notice that A4 was barricaded closed during a high-speed exit. Pilot's complacency and inattention to detail caused the main issue which was missing the A4 closure via NOTAMs. When giving and receiving briefings; make sure to verify all available NOTAMs. We were both familiar with DTW layout and operations however both pilots had not been to DTW in some time.




Synopsis: CRJ-200 pilot reported an inadequate briefing resulted in a taxiway excursion.
