Overview

During summer 2019, crews built southbound I-5 ramp meters between Lacey and Olympia. These ramp meters are located at Marvin Road, Martin Way East Sleater-Kinney Road Southeast, Pacific Avenue Southeast and Henderson Boulevard Southeast.

How you benefit

Multiple vehicles merging onto the highway at the same time contributes to southbound I-5 congestion between Lacey and Olympia. A platoon of merging vehicles will cause drivers using I-5 to change lanes or slow down. This has a cumulative affect that contributes to congestion.

Ramp meters pace the flow of merging traffic. A short wait at a traffic signal on the on-ramp helps break up the platoon of vehicles. When vehicles enter the highway in controlled intervals, those vehicles are less likely to disrupt highway flow.

Funding

The total project cost is $1.53 million.
