RIVER FALLS - An Elmwood teen is now in fair condition, while a Spring Valley woman has seen her condition improve as well, as both were involved in a  two-vehicle, head-on accident on Hwy. 29, about two miles east of River Falls late Wednesday afternoon.

Both were transported directly to Regions Hospital -- one by medical helicopter and the other by ambulance.

Pierce County sheriff's deputy Jean Spletstoser said Noah Wells, 17, of Elmwood, was westbound when his vehicle crossed the center line and struck an eastbound vehicle driven by Laura Johanson, 35, of Spring Valley. Wells has improved from serious to fair, a spokesperson said Monday, while Johanson is now serious after initially being listed as critical. 

Authorities were alerted at 4:16 p.m. Wreckage blocked both lanes of travel and motorists were diverted onto town roads or up to CTH M.

Both patients had to be extricated by River Falls firefighters. Wells was transported to Regions Hospital by River Falls EMS while Johanson was moved to a North Air Care helicopter that landed on 850th Street, a spokesperson said Thursday. 

The Wisconsin State Patrol assisted with a reconstruction of the crash and the Pierce County Highway workers brought barricades, closing Hwy. 29 for several hours as the investigation was completed.
