JACKSON, Wyo. (AP) — Work to expand and renovate St. John's Medical Center in Jackson has been halted while hospital officials look at ways to keep the project on budget.

Acting hospital CEO John Kren says estimates for supplies and labor are coming in between $2 million to $3.5 million over budget.

The Jackson Hole News & Guide (http://bit.ly/s7rY9u ) reports that revising the hospital project to reduce costs could delay work for up to four months.

The nearly $26 million project has been on hold since Nov. 28.

Work began in late August. Crews have demolished six primary care rooms and dug a hole for a foundation but have not poured the new foundation yet.
