The Posey Tube is the tunnel leaving Alameda, and heads to Oakland…read more Recently, traffic has been slowing down or just jammed up due to roadwork on the Oakland side. I heard about plans to do a major upgrade to the on ramps to I-880 and the roads leaving the Posey Tube. The roadwork hasn't been scheduled yet, but you can expect serious delays. I drive thru this Tube about 5-6 times a week. It's always dark, and you tend to lose radio reception underwater. I guess as long as it's not leaking water, we should be happy. Note: The Posey Tube is not named after Buster Posey, the baseball player.

The San Mateo/Hayward Bridge is a very important hub linking the peninsula to the southern part of…read morethe East Bay. Although, I'm not sure of the length of the bridge, it is quite a distance from one end to another, but it gives you beautiful views, when it's a clear and sunny day. One end will lead you to the Peninsula that will take you to San Carlos, Redwood city, and to the South Bay. That's the hub for the tech world. The other side will lead you to the East Bay, which will take you to, Hayward and eventually to Berkeley and Oakland. There will be a toll plaza on the eastern end of the bridge with standard going right for the area. Yes, the prices go up, but considering the convenience from going to one end of the bay area to the other, makes it worthy, especially if you drive during non-peak hours. The roads on the bridge are taken care of and although traffic can be an issue I don't see too many accidents leading to problems. Convenient and efficient that's what I love, especially when it comes to transportation.

The San Mateo-Hayward Bridge isn't anything amazing, although it does get you where you need to go…read morewith a price tag that doesn't seem worth it. It's longer than the other bridges, but nothing special. As of January 1st, 2026, it costs $8.50 to cross the bridge and there are several bridges in the bay area, so it feels that you get price gauged every time you cross any of them and not worth it. The amount of bridges in the bay area and the amount of price gauging is ridiculous. A series of 50-cent annual increases are in effect from 2026 to 2030 so you will continuously have to pay more year after year. The tolls are going up way beyond the rate of inflation and will continue to until 2030 and then they will have another tactic to increase it further. It's expected to be $10.50 to cross the bridge in 2030.

I am not too keen on the dumbarton bridge, it feels finicky, and the cost has gone up significantly…read moresince the decade from being $5 to around $8+ dollars now. I have driven on this bridge quite a lot especially a decade ago when I lived in the east bay and drove to the peninsula for work I don't like that it doesn't have the big poles or big railing; and the cars shake when driving over the bridge due to the wind. It was never my favorite bridge even a decade ago due to the shakiness, it's not good. I have arial photos from early 2020, thankfully the bridge is only 15 mins or so. But I think they could make it feel a bit more secure (I am sure structurally it's okay , the wind is wild though)

The Dumbarton Bridge as we know it today was opened in 1982. The original span was opened in 1927,…read moreand was the first vehicle bridge to cross SF Bay. Today's Dumbarton Bridge is 3 lanes in each direction, and has a pedestrian/bike lane. The span is only 1.6 miles long, and the bridge has no emergency shoulders. Seems longer than 1.6 miles right? I think they don't count the long approaches. I have never used the Dumbarton Bridge during the morning commute, I mostly use it in the evening going eastbound. I never really got stuck in traffic on this bridge. Being a modern span, I think traffic engineers did a good job designing the Menlo Park/Palo Alto approach. You can't please everyone, someone's going to sit in traffic during the commute. Notes: On the westbound approach, you will go pass the KGO-810 AM transmitter. In Menlo Park, at Willow Rd, on the right is Facebook HQs (formerly Sun Microsystems). Sometimes on the Newark side, there's a foul smell from the swampy marshlands. In 2023, the toll for a regular car is $7.00. There's no toll takers. Toll is collected by Fastrak Transponders or they take a photo of your license plate. The bridge links Newark (Eastbay) to East Palo Alto (Peninsula) via CA-84.

Driving through the Robin Williams Tunnel is one of the distinctive moments on the route between…read moreSan Francisco and Marin County. Set into the steep, wooded slopes of the Waldo Grade, the twin-bore tunnel carries Highway 101 through the hillside just north of the Golden Gate Bridge. Its rainbow-painted portals add a burst of color to the drive, especially when approaching from the San Francisco side, where the road curves through the hills and opens toward views of the bridge, bay, and Marin landscape. Originally built in 1937 as the Waldo Tunnel to create a faster- reliable highway connection through the challenging grade, the first bore was later joined by a second as traffic between San Francisco and the North Bay increased. It was renamed the Robin Williams Tunnel in honor of the late actor and comedian, who had deep ties to Marin County and lived in Tiburon for many years. The drive itself is brief, but it feels good : the light changes as you enter, the sound of traffic echoes around the tunnel walls, and the colorful arches signal that you are either arriving in Marin or heading back toward San Francisco. It is a practical piece of the Bay Area infrastructure, and also a cheerful and fitting tribute to Robin Williams--historic, useful, and full of local character.

Very few restaurants we like to frequent: Townhouse - One of our past favorites. Hong Kong East Ocean - This used to be "hot," especially when they first opened in 1989. But rarely do people use this place for events anymore. Well at least not my circle. Trader Vic's - Same as Hong Kong East Ocean... Since 1972! Wallys Cafe - Support local; a small mom and pop location. Arizmendi - A great bakery! Some attractions - Bay Street (my daughter's and wife's shopping). I don't even go to the theater here any more.
