JEFFERSON CITY, Mo. (AP) — Missouri lawmakers are entering their final day of work with time running short for contentious bills on guns, abortions and taxes.

The Missouri Constitution sets a 6 p.m. Friday deadline for lawmakers to pass bills. That typically creates a fast-paced finale. But it makes it easier for opponents to block bills.

Measures expanding gun rights and further restricting abortions are facing opposition from some lawmakers. Also lingering is a proposal asking voters to raise the fuel tax by nearly 6 cents a gallon for roads and bridges.

Some measures already have been defeated, including ones legalizing medical marijuana and allowing people with religious objections to deny wedding-related services to same-sex couples.

Others already have become law, including several new ethics measures and a change to the school funding formula.
