If you R traveling thru Sacramento going north on I5, just past the airport + across the Sacramento River you will come to the Yolo Causeway, just before the City of Woodland. The Causeway is in need of repair. The bumps at each joint of the Causeway are jarring. Recommend you consider taking State Highway 113 as an alternate route. I5 northbound to I80 westbound, to Hwy 113 northbound (just past UC Davis), back to I5 northbound at Woodland. If southbound on I5, take Hwy 113 at Woodland to I80 eastbound, back to I5 southbound. We have been taking this route for several years now, even when we lived in the Sacramento area.
