Narrative:

My first officer received ATIS information 'V' and called for our clearance. After a bit of a delay due to operations issues we closed the cabin doors; I called dispatch momentarily and then we started the engines; ran our checklist and called for a taxi clearance. We were issued 'taxi runway 10; east and a'. As I was beginning the right turn out of the gate ground control told us to use caution for company to our right. I saw our company aircraft to our immediate right (with little room to spare and jet bridge congestion) and continued our taxi straight ahead onto D. As soon as I did this I realized my error. Our instructions were to take east and a.before I could call ground control he contacted us and told us we had taxied onto a closed taxiway. I was not aware of the closure because the ATIS or notams did not state the taxiway was closed nor did the controller alert us to a new ATIS issuance when we requested taxi. The only taxi closures listed on the ATIS V and that were briefed on the flight deck were 'F north of a; a between G and C; and taxiway C'. There was no way our aircraft could have entered onto east with our company aircraft and jet bridge congestion on east as well. We were issued new taxi instructions which were 'M; B; a to runway 10.' better ATC communications; including updated ATIS and notams would have helped avoid this event. With a closure on a taxiway that is frequently used for our company's outbound aircraft (typically we are told to exit D and proceed on M; B and a) perhaps a verbal reminder from ground or some markings; cones; lights; etc. Indicating a closure would have been helpful and alerted me prior to committing my error. In closing I recognize my mistake and in the future will exercise more vigilance.

Title: When confronted with congestion on their cleared taxi route for takeoff; the Captain of a DHC-8 reverted to a frequent taxi route usually provided by ATC when Taxiway Delta wasn't closed; however; today it was and an incursion ensued. Ground Control reminded them and provided an alternative clearance.

After a bit of a delay due to operations issues we closed the cabin doors; I called Dispatch momentarily and then we started the engines; ran our checklist and called for a taxi clearance.
