By JOAN LOWYWASHINGTON (AP) — Donald Trump is vowing to rebuild the nation's roads, bridges, airports and railways, but the path to delivering on that promise is full of potholes. A Republican Congress fought President Barack Obama at almost every turn when he tried to do it. And Trump would have to contend with his party's deep-seated dislike for government spending and higher taxes if he is to generate as much $1 trillion in infrastructure spending as he has proposed. Yet transportation industry officials say Trump's enthusiasm for fixing the nation's infrastructure is reason for optimism. The Republican president-elect underscored the importance he accords the matter by making it the first policy issue he raised in his victory speech Wednesday. Trump said rebuilding infrastructure will "put millions of our people to work."
