The 1930 bridge is on Tacoma Avenue South between Center and Delin streets and carries traffic over South Tacoma Way and Sound Transit’s Sounder railroad tracks.
Construction on the $12 million project started Feb. 23. The job includes a new, wider bridge deck, streetlights, guardrails and a new paint job.
When the bridge reopens, vehicle traffic lanes will be reduced to three from the original four-lane configuration. The extra space will be used for wider sidewalks and two bike lanes.
Most of the funding is coming from a $9 million Federal Highway Bridge Program grant. A Transportation Improvement Board grant added $2 million, and the city chipped in with $1 million.
