Henry Thompson Bridge

The Henry Thompson Bridge over the Baker River in Concrete has the lowest sufficiency rating in Skagit County.

A recent report on the condition of Skagit County’s bridges found no major safety concerns.

The 2018 Bridge Inventory Report assigns sufficiency ratings to the 125 bridges in the county.

This is the first bridge report since the Old Highway 99 overpass north of Cook Road was replaced.

The old wooden trestle bridge — rated at a 3 out of 100 — had been the lowest-rated in the county.

The new concrete structure is the only bridge in the county rated at 100.

Three bridges in the county have sufficiency ratings in the 20s: the Henry Thompson Bridge in Concrete and the ferry docks in Anacortes and on Guemes Island.

At 20.8, the historic Henry Thompson Bridge over the Baker River in Concrete had the lowest score in the county, though Forrest Jones, traffic division manager with county Public Works, said the bridge doesn’t represent a safety concern.

“It’s just not able, at its age, to handle (semi-truck) loads,” Jones said.

He said the bridge is rated to handle 10 tons, which is about one-fifth of a legal truck load.

If a semi-truck was to cross the bridge, Jones said there might be a stability problem. However, he said the bridge’s weight limitation is clearly marked with signs.

The Guemes Island ferry dock and Anacortes ferry dock, with scores of about 24.1 and 24.6, respectively, have the next lowest scores in the county.

These scores are brought down by issues that don’t impact safety for drivers and that the docks are slated to be repaired either this year or next, he said.
