Portland's 14th annual Providence Bridge Pedal is Sunday morning, Aug. 9, and the good news for families is that participation for kids is free this year.
On the other hand, car drivers will need a plan on how to get where they're going Sunday morning -- especially if they're crossing the Willamette River between 5:30 a.m. and noon.
The bridge pedal opens up eight Willamette River bridges to bike traffic, including three organized bicycle routes and one for walkers.
The exhilarating annual experience allows citizens to walk or ride – and lounge – through what are usually major freeways, including the top deck of the Fremont Bridge, which offers astounding views of the river and the city.
The Burnside and St. Johns will remain open to vehicular traffic in both directions, despite the presence of cyclists. The Morrison and Steel bridges are not used by the event so those are good alternate crossings on Sunday.
Bridge sidewalks will remain open during the event.
Here is the traffic plan for Bridge Pedal, starting with bridges from south to north:

--The Sellwood Bridge will be closed westbound from 6 am to 9 am.
The Ross Island Bridge will be closed westbound from 6 am until as late as noon.
The Marquam Bridge/Interstate 5 will be closed northbound (upper deck) at 5:30 am and will reopen by noon.

--The Hawthorne Bridge will be closed to eastbound traffic from 6:30 am to 10:15 am, with TriMet bus service operating in both directions. One eastbound and one westbound lane will be closed beginning Saturday at 6 pm until noon on Sunday.

--The Burnside Bridge's outermost westbound lane and westbound bike lane will be closed from 7 am to 11 am.

--Broadway Bridge traffic lanes will be closed in both directions from 7 am to 12:30 pm.
The Fremont Bridge/Interstate 405 will be closed southbound (upper deck) at 5:30 am and will reopen by noon.
The St. Johns Bridge will have one lane open in both directions (the other two lanes will be closed) from 7 am to noon.

Bridge Pedal will also require traffic changes on several state highways and Portland streets Sunday morning, including:
--I-5 and I-405: During the temporary Marquam Bridge closure (from 5:30 am to noon) motorists approaching the Marquam Bridge from I-5 northbound will be routed to I-405 northbound, across the lower deck of the Fremont Bridge, back to I-5 northbound.
