Below is your situation.

Is there a way I can connect 3 LNBs (110, 119, &129) to 3 HD receivers with only 2 cables? I have only one location where I can get a clear shot through the trees and it’s across a concrete driveway. I only have 2 cables under the driveway. Is there a way to do this with a combination of switches?
If you want all 3 HD receivers to have access to all 3 satellites, then No you can not do it with 2 cables with your current equipment list/setup, regardless if the receivers are single and/or dual tuner receivers.

I'm currently using 61.5 but my HD locals are on 129. Can I get by with 2 cables if I only have 2 receivers and put the switch at the dish?
The DP34 switch (you have available) will not work with the Legacy LNBF's. However, you should be able to connect two SINGLE TUNER HD RECEIVERS using 2 SW21 legacy switches.
See below for possible options.

I'm using 3 individual dishes with legacy LNBs. So are you saying there is a way to hook up 3 single HD receivers?
Not with only 2 cables. With the legacy LNBF's, you might be able to with 3 cables; however,
if so, it would require splitters and legacy switches costing more than converting to DishPro and DishPro Plus.

I'm using one side of 500 twin for 110. I'm using a 24" dish for 119 (I have to shoot through trees). I'm using a single 500 dish for 61.5. The switch is a DP34.
This equipment list is not completely compatible, you are trying to mix Legacy with DishPro.
I'm not really sure what type of LNBF you have for the last 2 dishes, hopefully for "Option 1" below, one of them has a dual output even though it picks up a single location.
Not knowing if any of your setup has ever worked or not, and how you are determining that you even have the correct satellites,
I think you should strongly consider discussing your options with a local installer.
However, I'm a firm believer that everyone has the right to practice backyard mechanics, so here's a wrap-up if you decide to proceed on your own.
Option 1:
Depending on the LNBF's for your last 2 dishes, confirm your switch selections at
http://ekb.dbstalk.com/swconfig.htm
Buy 2 Dish Legacy SW-21 Switches.
http://www.sadoun.com/Sat/Order/Switches/DishNetwork-switches.htm
Use the Dish 500 Legacy Twin for 110 and 119, even if you have to shift it over or cut down the tree.
Each port on the D-500 Twin should go to a separate SW-21 Input.
The other SW-21 Input should come from a Legacy Dual LNBF on a 2nd dish pointed at 129. Use either the 24" Dish or the other Dish 500. However, if the LNBF on your 2nd and 3rd dishes each have only a single output, then point both dishes to 129 and let each feed a separate SW-21 Input.
Connect each SW-21 to a cable going under the drive way.
Connect the other end of each cable to a single tuner receiver (HD or SD).
Option 2:Buy 1 DishPro Twin LNBF, and 1 DishPro Dual LNBF.
http://www.sadoun.com/Sat/Order/LNBFS/DISHNETWORK-LNBF.htm
Use the Dish 500 Legacy Twin for 110 and 119, even if you have to shift it over or cut down the tree. Remove the Legacy Twin and replace with the DishPro Plus Twin. (Note: There are 3 types of Twins; Legacy Twin, DishPro Twin, and DishPro Plus Twin. You want the DP Plus Twin.)
Use either the 24" Dish or the other Dish 500. Remove the Legacy LNBF and replace with the DishPro Dual LNBF. Connect one of the outputs to the Input on the DPP Twin. Point and peak this dish for 129.
Connect the two cables going under the drive to the 2 outputs on the DPP Twin.
Connect the other end of each cable to a single tuner receiver (HD or SD). However, each cable could feed a Dual Tuner Receiver using a DPP Separator.
Option 3:
If you want to hook up 3 or more single and/or dual tuner receivers (upto 8 tuners).
You could use Option 2 above, but you will need to install the DP-34 switch on the other side of the driveway, near or inside the house.
The DPP Twin will feed the 2 cables going under the driveway.
However, you will need to remove the cable going to the DPP Twin Input and run it from the 2nd dish to the DP-34 switch.
Here's where you will need to be flexible. If you can't get it under the driveway, then mount the dish somewhere that you can pick up 129, and still run the cable to the DP-34 (as rich88 posted).
(Note: For this option, either the DishPro Plus Twin or the DishPro Twin should work.)
Caution!
I think the Dish 500 with DishPro Twin came out around 2000 and before that was the Dish 500 with Legacy Twin. Therefore, it sounds like you may have a old (or legacy
) installation.
If this cable has been in the ground under the driveway for awhile, it may be deterioated. More importantly, it may be RG-59 which even if brand new, isn't recommended for a DishPro job which should be RG-6 rated at least for 2150MHz.
