Why is the Calf Robe bridge still such a disaster?

[revelations]

Could someone tell me why the repaired calf robe bridge has such an uneven road surface? I've never seen a recently finished road surface on a major roadway in such bad condition.

Is it because it is concrete?

[narou]

Doesn't look finished too me. Honestly it was better before they started doing work on it.

I don't really think so. Lots of US cities have concrete highways, and they're freaking beautiful to drive on (not as good as properly done asphalt, but still nice).

Oh you have never been to houston then. It is pretty much all concrete and is like thunk thunk thunk thunk thunk over and over but you get used to it.

^ Yeah I've driven thousands of MILES on concrete I highways in the states.... they are smooth roads with the exception of the seams.



I wonder if this is partially why motorists tend to hit the brakes and slow to 80kph on the bridge - on a clear day with no traffic - because they freak out at the corner and then the unsmooth road.

Most states that have concrete dont get frost heaves.

hitler used to build amazing concrete autobahns, there aren't many left but i've driven on them before they were

The calf-robe doesn't get many frost heaves either, lol. Seriously though, it wasn't good after they were finished in the fall, with no sub-zero temps.

I don't know, but I've noticed the same shoddy road construction all over Calgary (with the exception of Stoney, which seems to be done very well). I remember when they finished Glenmore between about Centre and Crowchild... you could drive along the thing and it was all bumpy and uneven like some guys had built it using shovels and non-motorized tampers. and this is one of the main thoroughfare freeways in the city.

It seems that the city has really poor oversight of the road contractors, and lets them get away with half-assed shit work (which many contractors try to get away with if you aren't keeping on them).

Does anyone have some historical perspective on the CR bridge?

- why was it built with such a sharp S curve?
- why isnt the surface grooved like the 4th ave flyover into downtown?
- who was the winning civil engineer that conceived the OLD WB Peigan Tr to SB deer foot "onramp" where you had 2 seconds to merge.

It's a city contract. the builder could use an open bottom port-o-potty as a paving machine and the city would still pay top dollar.

same with stoney trail. Calgary's newest road and it's spent more time being under construction to put patches on top of patches than it has spent open. (yes, i'm aware its technically an alberta highway)

I'll still never understand why the city allows contractors to put 3-4 employees on one job for 4 months. instead of putting 10-12 workers on one job for a couple weeks THEN moving onto the next job.

My guess is because north and south of the calf robe deerfoot trail runs roughly parallel to the bow. The turn is sharp because you want bridges to be as short as possible so you need to get perpendicular to the river to minimize the distance. The only way of doing this with a less tight corner would be to move the north end east and the south end west to increase the radius of the turn.

I know nothing about deerfoots history but my guess was when it was built they didn't build it to accommodate a 100kph speed limit and/or historical land issues prevented them from creating larger radius turns.

I'm pretty sure Deerfoot is taken care of by the province, not the city...

They did shave one section of the new surface ( NB far right lane and 1/2 the middle lane on the northern [2nd] bridge) and it's not bad...

I'm also pretty sure it's impossible to get frost heaves on a bridge deck because there's air under the deck and not frozen earth.

The bridge is complete shit.
Always has been, and I lost hope last year that it would ever get better.

[black13]

Seriously agree. What a piece of shit road. I thought maybe after winter it would even out a bit but with the warm winter, don't think it helped.

It's a sharp turn and its bumpy.

Yeah, it's complete garbage. Even with the whole construction during last year, I thought there would be improvements but it's bumpy as hell. I feel sorry for anybody with a slammed ride.

Deerfoot trail isn't built to handle rush hour traffic today. Hopefully the ring road helps in that regard once that project is complete.

Way too many spots on deerfoot where 3 lanes go into 2 and on/off merge lanes in same spot that aren't very long + absolutely terrible (scared) drivers who HAVE to merge right at the beggining of the lane = traffic jams.

I've heard Calf Robe is in Civic Eng textbooks as an example of how NOT to build a bridge.

It was actually a yield, which made things even more interesting.

For the next edition they need to add the northbound crowchild trail bridge over the bow.
