A missionary from Central Massachusetts who is “in the middle of the craziness” in Haiti sparked by a now-rescinded government plan to raise fuel prices in the impoverished nation said things are calming down and getting back to normal.

On Sunday, the U.S. State Department issued an alert urging its citizens in Haiti to shelter in place and not to go to an airport unless travelers had confirmed their departing flight was taking off.

Despite the warning, Scott Long, the president and founder of Mission E4, a nonprofit para-church ministry based in Hubbardston, traveled from Léogâne, Haiti, on Sunday to the Toussaint Louverture International Airport in Port-au-Prince.

“We’re down in Haiti in the middle of the craziness but we’re doing well,” Mr. Long said on his cellphone. “They had the road blocked with rocks and/or tires probably every 300 to 400 yards. I ran across 300 roadblocks to block the road to keep traffic from circulating.”

Protests erupted Friday hours, before the government-set price of fuel was to rise by up to 50 percent. Subsequently, the Haitian government canceled the increase amid protests that left several people dead and prompted airlines to cancel flights over the weekend.

Mr. Long said he hasn’t seen the streets of Haiti blocked up at the levels they were on Sunday since 2004 coup d'état in which Haitian President Jean-Bertrand Aristide was removed from office.

“Based on the magnitude of what I saw, it was clearly not just a couple gangs. It was clearly not just one political party. It was, really, a good portion of the population that rose up,” Mr. Long said. “They literally wanted to shut the country down. They wanted to shut traffic down. They wanted to shut business down. They wanted to shut down people coming in and out of the airline. They wanted to send a big message to the government that they’re not going to nor can they accept the price increase in fuel that was coming.”

Before sunrise Sunday, Mr. Long traveled 25 miles to get to the airport to meet one of his mission’s associates, Paul Occhipinti of Princeton.

“We took a couple of tap taps (shared taxis). We had to take one for about three miles. Then we he hit a place where we could absolutely not pass,” Mr. Long said. “So we got off and we had to walk on foot for about three miles. Then we found another vehicle that took us another three or four miles. He couldn’t go any further than that. We had to walk on foot again for another two or three miles. And then we finally got a couple of motorcycles to take us the rest of the way to the airport.”

On Monday, Mr. Long saw Franklin Town Councilor Glenn Jones, who also was in Haiti to do work for Mission E4, depart from the same airport with no problem.

Mr. Long, who had flown to Haiti on Wednesday, said most of the roads from Port-au-Prince to Léogâne were pretty clear Monday.

“As a whole, thing are really beginning to calm down," Mr. Long said. "We’re all hoping, by tomorrow (Tuesday), things will be getting a little bit more back to normal.”

Despite the protests, Mr. Long said, the mission workers' travels have stayed on schedule and he and his American comrades are not worried about his safety.

“This wasn’t just some senseless act of violence that was going on. These people are suffering. And this was a protest against a gas hike that the government has been proposing,” Mr. Long said. “This is a country where most people make barely over a dollar a day. So when you’re talking an increase in fuel cost at 40 percent, obviously, it’s not just affecting vehicles. It’s affecting the price of rice. It’s affecting the price of everything, because once fuel costs go up, everything goes up. It’s substantial.”
