One alternative would run streetcars through downtown on Broadway and Robinson Avenue.
Others would push streetcars a few blocks west for part of the way, providing a connection to the Downtown Transit Center.
Two alignments that would bring riders in one case to the park and in another to within one block came in on the high end of the cost estimates, with price tags of $97 million to $109 million.
A plan labeled Zeta Plus would connect all seven of the preferred destinations with 4.4 miles of track. Other alternatives ranged from 4 to 4.6 miles in length.
MAPS 3 plan
The proposed transit improvements are part of the $777 million MAPS 3 building program funded by a penny sales tax.
Phase 1 of the streetcar project is to link MidTown, downtown and Bricktown, at a cost of $94.4 million for the rails and $9.75 million for the remodeled railroad depot.
Phase 2 would run streetcars from downtown through the Deep Deuce neighborhood.
Rails eventually could skirt the Lower JFK neighborhood on the way to the Oklahoma Health Center.
