AUSTIN, Texas (AP) — Voters have gone to the polls to decide nine proposed amendments to the Texas Constitution including a $2 billion water projects plan.

Polls opened across much of Texas at 7 a.m. CST Tuesday. Voters in far West Texas could start casting ballots as of 7 a.m. MST.

It's the first Election Day in Texas under a new photo ID law. Voters must present photo identification — such as a driver's license, a passport or a military ID — to cast ballots.

State election officials say early voting, which ended Friday, nearly doubled from 2011, when the last off-year elections were held in Texas. More than 317,000 people have already voted in the state's 15 largest counties, up from 168,000 early voters two years ago.

The polls close at 7 p.m. Tuesday.
