- DUPONT – If April showers bring May flowers, then April girder setting will bring a new overpass, eventually, to a heavily used Interstate 5 intersection in DuPont. Nighttime travelers who use I-5, or the Steilacoom-DuPont Road overpass in DuPont, will see some delays and detours in April. Over two weekends, construction crews working for the Washington State Department of Transportation will place 13 girders over I-5, just north of the existing Steilacoom-DuPont Road overpass.
- OLYMPIA – Good To Go! is asking people to be cautious as scammers are impersonating toll agencies nationwide. They are attempting to trick people into making payments and sharing their banking information.
- OLYMPIA – Studded tires must be removed by the end of the day Monday, March 31 to avoid a potential fine of $137. Automotive centers are expected to be busy the weekend before the deadline, so the Washington State Department of Transportation encourages travelers to plan ahead.
