Lincoln police arrested the driver suspected of crossing the median on Superior Street, hitting a construction worker in a coned-off work area and then trying to drive off Wednesday afternoon.
Prosecutors have charged Janet Lubben, 78, with DUI causing serious bodily injury and leaving the scene of an injury accident.
The 34-year-old construction worker, identified by police as Gromyko Roby of Omaha, remains hospitalized at Bryan West Campus with life-threatening injuries, Officer Angela Sands said.
Lubben was driving on the median at 2:41 p.m. when she hit Roby, who was walking on the median back toward his pickup, Sands said.
The car continued westbound in the eastbound lanes toward 27th and Superior and stopped near Industrial Avenue, according to police.
Lubben was unconscious when contacted by officers and didn't cooperate when asked for a blood-alcohol test later at the jail, Sands said.
Police suspect Lubben's vehicle jumped a median once prior to hitting the median and striking the worker, Sands said.
Initially, witness reports indicated Lubben had suffered a medical episode, but police said she was taken to the hospital, medically cleared and taken to jail.
Officers do not know where she had been prior to the crash because she was not cooperating with investigators, Sands said.
Lubben appeared in Lancaster County Court from jail via video monitor, and a judge set her bond at $15,000. She's been ordered not to drive or consume alcohol if she posts bail.
If convicted, she faces up to six years in prison.
