Narrative:

When we pushed from [gate]; clearance informed us we had 9 minutes to wheels up. Ground control gave us: 'C; B2; B; D; for runway xx.' as we approached the end of the north ramp/western ramp area short of runway xx; we saw barricades as NOTAM'd. We slowed and I looked down at my -9 page and stated we take a right on B and right on D. I heard the captain (ca) say 'huh' and I looked back at my -9. I felt the aircraft moving and looked up to see we had turned left on D and were crossing runway xy. Ground control stated we had crossed an active runway and told us to hold short H. The ca returned the call acknowledging the mistake. We were then told right H; right a; cross runway xy; short runway xx at C. At that point ground control told us they would be making a call about a pilot deviation and to contact tower. We contacted tower and were cleared for takeoff.threats: (1) rushing to make our wheels up time (2) the barricades at the north west end of the ramp which appeared to block the route.errors: we should have stopped the aircraft to confirm the route when it became apparent that there was confusion. We should have confirmed clearance to cross runway xy. I should have been more assertive in my understanding of the instructions. I should not have relied on what I perceived as the ca's familiarity with the airport.unwanted situation: (1) crossing an active runway without clearance; (2) loss of situational awareness.even when flying with a veteran ca; it is critical to check/cross-check all clearances on the ground and in the air. Even the best intentioned crews operating within company and FAA SOP's are susceptible to errors.

Title: An EMB-145 flight crew incurred a runway while rushing for a time constrained takeoff with complex taxi instructions because of a closed taxiway.

Narrative: When we pushed from [gate]; clearance informed us we had 9 minutes to wheels up. Ground control gave us: 'C; B2; B; D; for RWY XX.' As we approached the end of the north ramp/western ramp area short of RWY XX; we saw barricades as NOTAM'd. We slowed and I looked down at my -9 page and stated we take a right on B and right on D. I heard the Captain (CA) say 'huh' and I looked back at my -9. I felt the aircraft moving and looked up to see we had turned left on D and were crossing runway XY. Ground control stated we had crossed an active runway and told us to hold short H. The CA returned the call acknowledging the mistake. We were then told right H; right A; cross RWY XY; short RWY XX at C. At that point ground control told us they would be making a call about a pilot deviation and to contact tower.
